An ad hoc network is a collection of autonomous mobile nodes to forming an instant multihop radio infrastructure-less network in a dynamic topology. Each node in Ad hoc network, functions as host and router at the same time, where maintaining connectivity in a decentralized manner by distributing the network control among the nodes. Many routing protocols for mobile ad-hoc networks are presented since last decade. Topology frequently changing, transmission power and asymmetric links are the main challenge that types of protocols is facing. This has led to development of many different routing protocols for networks. In this review work, we provided an overview of a wide range of routing protocols proposed in the literature till date. To the best of our knowledge, this is the first paper that studies nearly 52 existing routing protocols in Ad hoc Networks.

Mobile ad hoc networks (MANETs) are created by the mobile computing devices on an ad hoc basis without any support provided by a pre-installed communications infrastructure. Along with their appealing properties, MANETs exhibit properties that hinder their realization. Topology dynamism and bandwidth limitations adversely affect the performance of MANETs routing protocols. Virtual backbone is proposed to facilitate routing, broadcasting, and establishing a dynamic infrastructure for distributed location databases. Minimizing the virtual backbone size produces a simpler abstracted topology of the MANET and allows for using shorter routes. In this book, a comprehensive study of MANETs routing and clustering algorithms is presented along with a simulation- based performance evaluation of the most renowned algorithms using the NS2 network simulator. This comparison focuses on the total costs incurred in terms of CDS size, running time, and signaling overhead generated during the CDS creation and maintenance phases. Moreover, the effects of mobility rates, network size, and mobility models on the performance of each algorithm are investigated.

Mobile Ad hoc Network (MANET) is a system of wireless mobile nodes that dynamically self-organize in arbitrary and temporary network topologies without communication infrastructure. This network may change rapidly and unpredictably. Application of ad hoc networks includes Academic Environment Applications, Health Care Applications, Military Applications, Bluetooth, and Personal Area Network. A service can be any tangible or intangible thing that can be useful for someone, a service can be a hardware service like a printer that can be used by a mobile device to print a file. Service discovery is defined by using one or two of Pull and Push Mechanisms. Security is a main challenge in MANETs. We propose a Secure Service Discovery Protocol for ad hoc networks (SPDPh). Simulation results of (SPDPh) and (PDP) using simulator (Ns-2) shows the extent of efficient secure service discovery protocol for ad hoc networks.

Master's Thesis from the year 2013 in the subject Computer Science - IT-Security, grade: C, Lovely Professional University, Punjab (School Of Computer Science and Engineering), course: M.Tech(CSE), language: English, abstract: The rapid proliferation of Mobile ad hoc network has changed the landscape of network security. The recent DOS attacks on major Internet sites have shown us, no open computer network is immune from intrusions. The ad-hoc network is particularly vulnerable due to its features of open medium, dynamic changing topology and cooperative algorithms, lack of centralized monitoring and management point and lack of a clear line of defense. The traditional way of protecting networks with firewalls and encryption software is no longer sufficient and effective. There are many intrusion detection techniques have been developed on Ad hoc network but have been turned to be inapplicable in this new environment. Here we need to search for new architecture and mechanisms to protect Mobile Ad hoc network. In the above all technique of intrusion detection is applied on the only one layer and that is probably on routing layer. But here we apply this intrusion detection system in the MAC layer for the more security, efficiency and high speed compare to other technique those whose apply in the network layer.

Random SALOHA and CSMA protocols that are used to access MAC in ad hoc networks are very small compared to the multiple and spontaneous use of the transmission channel. So they have low immunity to the problems of packet collisions. Indeed, the transmission time is the critical factor in the operation of such networks. The simulations demonstrate the positive impact of erasure codes on the throughput of the transmission in ad hoc networks. However, the network still suffers from the intermittency and volatility of its efficiency throughout its operation, and it switches quickly to the saturation zone. In this context, game theory has demonstrated his ability to lead the network to a more efficient equilibrium. This, we were led to propose our model code set that formalizes the behavior of nodes during transmission within SALOHA networks and CSMA respectively

Research Paper (postgraduate) from the year 2007 in the subject Computer Science - Internet, New Technologies, grade: PG, VIT University (Net Research Labs), 26 entries in the bibliography, language: English, abstract: One of the major challenges faced by MANET researchers is the deployment of end-to-end quality-of-service support mechanisms for streaming media services over a group of MANET users. Group-oriented services over large, dynamically changing MANET networks has a big impact on the needs of streaming services communication in terms of mobility, quality of service (QoS) support and multicasting. In MANET networks, where such features are not embedded with its architecture, it is necessary to develop QoS multicasting strategies. The research work focuses on the basic building blocks of an mobile ad hoc group communication scheme, which achieves multicasting optimal QoS efficiency OptiQ by tracking resource availability in a node's neighborhood based on resource reservations, which announces the required QoS before each session initiation. The primary quality of service (QoS) issues such as required bandwidth, message delay, traffic type and hop count per route improves the efficiency of streaming services over ad-hoc network. Streaming services support voice, data and video traffic by assessing and adjusting for various levels of QoS. The performance analysis is performed on functional prototype of OptiQ in mobile / wireless ad-hoc network with emphasis on servic...

Mobile Ad hoc Networks (MANETs) are dynamic networks populated by mobile stations or mobile nodes (MNs). Specifically, MANETs consist of a collection of nodes randomly placed in a line (not necessarily straight). MANETs do appear in many real-world network applications such as a vehicular MANETs built along a highway in a city environment or people in a particular location. MNs in MANETs are usually laptops, PDAs or mobile phones. These devices may use Bluetooth and/or IEEE 802.11 (Wi-Fi) network interfaces and communicate in a decentralized manner. Mobility is a key feature of MANETs. Each node may work as a router and the network can dynamically change with time; when new nodes can join, and other nodes can leave the network. In this thesis, comparative results of the Queueing Mobility Model and mobility models such as random walk/Brownian model have been carried out via Matlab software simulation. The study investigates the impact of mobility prediction models on mobile nodes' parameters such as the speed, the arrival rate and the size of mobile nodes in a given area. The results have indicated that mobile nodes' arrival rates may have influence on MNs population.

In this article I have conducted a performance study of DSDV, DSR, and AODV routing protocols in Mobile Ad-hoc Networks (MANETs). I have evaluated the effect of speed, TCP types, and maximum queue length on throughput and the effect of speed on number of packet drops.I have compared the performance of DSDV (Destination Sequenced Distance-Vector) from the Proactive family with the second type is AODV (Ad-hoc On-Demand Distance Vector) from the Reactive family. I used a detailed simulation model to demonstrate the performance characteristics of these protocols. By simulating we can argue that if delay is main criteria than DSDV can be my best choice but if reliability and throughput are main parameters for selection then AODV gives better results compared to others because its throughput and packet delivery ratio is best among others. While there are many other issues that need to be considered in analyzing the performance of ad-hoc networks, I believe that our work could provide intuition for future protocol selection and analysis in ad-hoc networks.

Ad hoc networks have a great importance in modernscientific and technological usage. Ad hoc networkdoes not need a topology,infrastructure and specialmanagement. Security limits its functionalityspecially in unsecured environment. This work comesto solve this problem by modifying one of the usedprotocols in ad hoc networks, which is Ad HocOn-demand Distance Victor(AODV) routing protocol thatdepends on finding route path just when need to. Thismodification has done by using some reserved bitsfrom Route Request(RREQ) packet to add securityfeature by selecting encryption algorithm to protectpayload data that is transferred between nodes ofcommunication by considering workload level at eachnode when selecting route path. In addition, thiswork presents a technique for distributing public keyto be used within RSA algorithm by adding a new partto RREQ packet. The performance of the standard andmodified AODV protocol also studied in this work byconsidering some parameters that affect ad hocnetwork performance, which are mobility and number ofnodes while communication process.

Mobile Ad hoc Networks or MANETs are networks in which multiple nodes, each possessing a wireless transceiver, from a network among them via peer-to-peer communication. There has been significant research activity over the past 5-10 years into performance of such networks with the view to develop more efficient and robust communication protocols. However, the vast majority of the research has concentrated on either developing appropriate mobility models for node movement or on developing performance metrics. The channel itself has been ignored. Some previous work had been done using Rayleigh channel model and Log-Normal model. However this work is based on Ricean channel fading model, which have not done till date.In the current work a more realistic wireless channel model is considered. In particular, we will consider one of the most well known wireless channel models, Ricean fading channel model. In this documentation, effects on the performance of mobile ad hoc networks due to presence of fading in Ricean channel is done by simulating experiments on QualNet simulator and then analyzing them.

Ad hoc mobile devices heavily depend on the performance of batteries. Optimizing the power consumption is a very crucial issue. To maximize the lifetime of mobile ad hoc network, the power consumption rate of each node must be reduced. In this paper we present a novel energy efficient routing algorithm based on mobile agents to deal with the routing mechanism in the energy-critical environments. A few mobile agents move in the network and communicate with each node. They collect the network information to build the global information matrix of nodes. The routing algorithm chooses a shortest path of all nodes in all possible routes. Additionally, we compare the performance of power-relation routing protocol DSR (Dynamic Source Routing)in simulation environment. The results show that the survivability of Ad Hoc network has been better because of less energy consumption when usingour improved DSR as compare to standard DSR protocol.

Bachelorarbeit aus dem Jahr 2008 im Fachbereich Informatik - Internet, neue Technologien, Note: 1,0, Fachhochschule Technikum Wien, Sprache: Deutsch, Abstract: Mobile ad hoc networks (MANETs) are networks of wireless mobile nodes without fixed infrastructure. Due to the highly dynamic topology there are special demands for routing protocols. Many routing protocols for MANETs have been proposed.This paper deals with both a classification of MANET routing protocols and a review of the protocols AODV, OLSR, CBRP, FSR, ZRP and GPSR. Some results are presented, derived from the extended simulations that have been performed with the NS-2 network simulator, in order to compare the efficiency of the above protocols with respect to Paket Delivery Ratio, Average End-to-End Delay, Path Optimality and Throughput. Simulationresults show that in terms of Paket Delivery Ratio and Throughput most protocols perform worse in larger networks with many nodes than in smaller ones with less nodes.

In this work, we introduce new path diversity schemes in order to provide robustness for both unicast and multicast video communi­cation applications over wireless ad hoc networks. We first propose a general architecture for multipath video streaming over wireless ad hoc networks. Then for the unicast case, we propose multipath strea­ming with two node-disjoint paths, which have minimum concurrent Packet Drop Probability (PDP) among all path pairs. This approach minimizes the probability of concurrent loss of all the descriptions, thus optimizing the worst case Multiple Description Coding (MDC) video quality over all times. Based on our path selection model, we propose a heuristic PDP aware multipath routing protocol. For the multicast case, we propose multiple tree video multicast with MDC. Specifically, we propose two distributed protocols, Serial Multiple Disjoint Tree Multicast Routing (Serial MDTMR) and Parallel Multiple Nearly-disjoint Trees Multicast Routing (Parallel MNTMR). We show video quality of proposed protocols are significantly higher than that of other protocols, through extensive NS simulations and actual experiments.

We use the simple and efficient mechanism to improve the performance of ad-hoc On-demand protocols. We use more than one path at a time but only one active route for destination. This approach reduces overhead of the route maintenance at the time of link failure. When path failure occurs there is other route is available to the destination. We use the RREQ packets and made more than one RREP packet for more than one route. We compare our ad-hoc on-demand protocol with other ad-hoc on-demand protocols like DSR, AOMDV and AODV. Our approach reduces the normalized routing load and Dropping ratio then other ad-hoc on-demand protocols. It also reduces the end to end delay than other ad-hoc on-demand protocols.

In this book, the problem of finding a path from asource to a destination node in a mesh of mobilewireless nodes is considered. One class of solutionsto this problem is based on the position-basedrouting paradigm, whereby the forwarding nodes relysolely on the knowledge of their geographicallocation (which can be established, e.g., via GPS),the location of their neighbors, and the location ofthe destination. This book proposes several newrandomized position-based algorithms for routing inmobile ad-hoc networks. The proposed algorithmsincorporate two heuristics: greedy aimed atminimizing the remaining distance of the packet tothe destination, and compass striving to minimize thepacket's deviation from the direction towards thedestination. Additionally, the routing decisions arerandomized - for improved flexibility and reliabilitycommunication. Experimental results obtained forvarious network topologies show that the deliveryrates of our randomized algorithms are significantlybetter than those attained by the deterministicvariants of the same heuristics.

Vehicular Ad-Hoc Networks (VANETs) play a key role to develop Intelligent Transportation Systems (ITS) aiming to achieve road safety and to guaranty needs of drivers and passengers, in addition to improve the transportation productivity. One of the most important challenges of this kind of networks is the data routing between VANET nodes which should be routed with high level of Quality of Service (QoS) to ensure receiving messages in the time. Then, the driver can take the appropriate decision to improve the road safety. In the literature, there are several routing protocols for VANETs which are more or less reliable to reach safety requirements. In this book, we start by describing all VANET basic concepts such as VANET definition, VANET versus Mobile ad-Hoc Network (MANET), architectures, routing definition and steps, Quality of Service (QoS) for VANET Routing, Metrics of evaluation, Experimentation, and simulation of VANETs, mobility patterns of VANET etc. Moreover, different routing protocols for routing in VANETs will be described. We propose two main categories to be presented: classical routing and bio-inspired routing. Concerning classical VANET, main principles and all phases will be overviewed, as well as, their two sub-categories which are topological and geographical protocols. After that, we propose a new category called bio-inspired routing which is inspired by natural phenomenon such as Ant colony, Bee life, Genetic operators etc. We present also, some referential protocols as example of each category. In this book, we focus on the idea of how to apply bio-inspired principle into VANET routing to improve road safety, and to ensure QoS of vehicular applications.

The book offers a comparative analysis of ad hoc and institutional arbitration, contributing to the existing professional literature with the aim to assist the parties making a pertinent choice. The advantages and disadvantages of both procedures are presented in the different procedural phases, unveiling the risks and difficulties that one may encounter and offering recommendations to avoid pitfalls and dead-ends. As different constructions may be suitable for different situations, depending on the particularities of each dispute and business relation­ship in part, and also depending on the parties' priorities, this book does not offer a recipe to suit each and every case. The general opinion favoring institutional arbitration is mostly supported for reasons of ease and due to the high risks of improperly constructed ad hoc proceedings, but the advantages of ad hoc arbitration, if properly administered, are also recognized, admitting the potential primacy of this alternative for certain cases.This book will hopefully make a useful contribution to make a suitable choice when opting for ad hoc or institutional arbitration.

The exponential growth of interconnection networks transformed the communication process into an important area of research. One of the fundamental types of communications is one-to-all communication, i.e. broadcasting. Broadcasting is an information dissemination process, in which one node, called the originator, disseminates a message to all other nodes by placing a series of calls along the communication lines of the network. One of the main problems in broadcasting is the minimum broadcast graph problem. Minimum broadcast graphs are the sparsest possible networks of this type, which have the minimum number of communication lines denoted by B(n) where n is the number of nodes in networks. Until now, B(n) is known only for a few general broadcast graph families and for some particular, mostly small values of n. For all n ≤ 32 B(n) is known, except for n = 23, 24 and 25. These cases were subject of our study. We introduce the case-by-case analysis of each of these graphs in order to determine the lower bound on B(n). Our results improved previously known lower bounds and can be used in future studies to construct minimum broadcast networks on 23, 24 and 25 nodes.

Green communications is a very hot topic. As mobile networks evolve in terms of higher rates/throughput, a consequent impact on operating costs is due to (aggregate) network energy consumption. As such, design on 4G networks and beyond have increasingly started to focus on `energy efficiency’ or so-called ‘green’ networks. Many techniques and solutions have been proposed to enhance the energy efficiency of mobile networks, yet no book has provided an in-depth analysis of the energy consumption issues in mobile networks nor has detailed theories, tools and solutions for solving the energy efficiency problems. This book presents the techniques and solutions for enhancing energy efficiency of future mobile networks, and consists of three major parts. The first part presents a general description of mobile network evolution in terms of both capacity and energy efficiency. The second part discusses the advanced techniques to green mobile networks. The third part discusses the solutions that enhance mobile network energy efficiency as well as provides future directions. Whilst the reader is expected to have basic knowledge of wireless communications, the authors present a brief introduction of the evolution of mobile networks, providing the knowledge base for understanding the content of the book. In addition, complicated network problems are illustrated using simple examples. This will help the reader understand the concept and intuition of various techniques and solutions. Incorporates the latest research results from both academia and industry, providing an up-to-date overview of existing technologies and solutions on making mobile networks greener Consists of three sections with a gradually increasing technical depth on green mobile networks, providing the reader with a systematic view of the research area, and helping those with different technical backgrounds to better understand the content Covers existing enabling technologies for green mobile networking, including an innovative discussion of state-of-the-art solutions and algorithms

Doctoral Thesis / Dissertation from the year 2017 in the subject Computer Science - Miscellaneous, , course: Ph.D Computer Science, language: English, abstract: Routing and Energy Efficiency is regarded as highly challenging area of Sensor networks. Significant advancements in Wireless Sensor Networks (WSNs) opens doors for wide implementation in real-time applications like Industrial Monitoring, Smart Cities development, Underwater monitoring operations, tracking objects and many more. Energy Efficient routing is regarded as the most challenging task. Sensor networks mostly operate in complex and dynamic environments and routing becomes tedious task to maintain as the network size increases. Lots of routing protocols- Reactive, Proactive and Hybrid are proposed by researchers but every protocol faces some limitations in terms of energy, routing, packet delivery ratio and security. Therefore, to overcome all the routing issues, the trend has shifted to Biological based Algorithms like Swarm Intelligence based techniques. Ant Colony Optimization based routing protocols have demonstrated exceptional results in terms of performance when applied to WSN routing. This thesis outlines routing protocols in sensor networks, highlight the concept of Swarm Intelligence and presents various Ant Colony Optimization based routing protocols for sensor networks. In addition to this, we present Ant Colony based Energy Efficient routing protocol (IEEMARP = Improvised Energy Efficient Multipath...

Recent advances in communication technology are enabling implementation of different types of network in various environments. One such network is Mobile Ad-Hoc Network (MANET). The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic which is done by several routing protocols. The design problem of such a routing protocol is not simple since an ad-hoc environment introduces new challenges that are not present in fixed networks. With the advent of the scenarios seeking infrastructure-less network with wireless nodes, security concerns have made the required personnel to mull over the MANET configuration using different protocols for various sized networks. This work is carried out to simulate the MANET using GloMoSim and to propose the enhancement in the quality of service by addressing the security concerns that loom on this specific network.The project discusses various categories of protocols proposed for the MANET, applications that are found out of this network, overview of the AODV protocol and most importantly the simulations that are carried out.

Diploma Thesis from the year 2001 in the subject Electrotechnology, grade: 1,7, University of Ulm, 34 entries in the bibliography, language: English, abstract: In today's world, there are mainly two types of communication networks: circuitswitched networks and packet-switched networks. The current telephone networks are mostly based on the circuit-switched networks, whereas the Internet is mainly based on the packetswitched networks, which are also called IP networks. However, there is a strong tendency to combine both of these networks, which points to the direction that the IP networks are going to replace services provided by current telephone networks. This would eventually mean that IP networks might replace the telephone networks, in the future.Following are some reasons why IP networks seem to replace the circuit-switchednetworks:· First of all, the IP networks provide cheaper communication. Considering thatthe Internet access is nearly free, the cost advantage of IP networks gets clearer[25].· Secondly, IP networks provide the ability of integrating the data and voiceapplications, and even some other applications, like video-conferencing,integrated voice mail, e-mail, and the like [26].· Another important reason is that IP networks allow open implementation ofend systems.

The Vehicular ad-hoc network (VANET) is an important communication paradigm in modern-day transport systems for exchanging live messages regarding traffic congestion, weather conditions, road conditions, and targeted location-based advertisements to improve the driving comfort. In such environments, authentication and privacy are two important challenges that need to be addressed. There are many existing works to provide authentication and privacy in VANETs. However, most of the existing authentication schemes are suffering from high computational cost during authentication and high communication cost during secure key distribution to a group of vehicles. Moreover, in many existing schemes, there is no conditional tracking mechanism available to revoke the misbehaving vehicles from the VANET system.In order to overcome these issues, four new approaches have been developed in this research work: Firstly, a dual authentication scheme is developed to provide a high level of security on the vehicle side to effectively prevent the unauthorized vehicles entering into the VANET. Moreover, a dual group key management scheme is developed to efficiently distribute a group key to a group of users and to update such group keys during the users' join and leave operations. Secondly, in order to preserve the privacy of vehicle users, a computationally efficient privacy preserving anonymous authentication scheme (CPAV) is developed to anonymously authenticate the vehicle users based on t...

This book introduces various coverage control problems for mobile sensor networks including barrier, sweep and blanket. Unlike many existing algorithms, all of the robotic sensor and actuator motion algorithms developed in the book are fully decentralized or distributed, computationally efficient, easily implementable in engineering practice and based only on information on the closest neighbours of each mobile sensor and actuator and local information about the environment. Moreover, the mobile robotic sensors have no prior information about the environment in which they operation. These various types of coverage problems have never been covered before by a single book in a systematic way. Another topic of this book is the study of mobile robotic sensor and actuator networks. Many modern engineering applications include the use of sensor and actuator networks to provide efficient and effective monitoring and control of industrial and environmental processes. Such mobile sensor and actuator networks are able to achieve improved performance and efficient monitoring together with reduction in power consumption and production cost.

Mobile communication is an integrated part of our daily lives. It surrounds us, and provides a ubiquitous communication channel even for the most demanding multimedia services. The focus of mobile communication shifts from voice to mobile broadband data services. Mobile operators are introducing novel techniques, such as High Speed Packet Data (HSXPA) and UMTS LTE (Long Term Evolution), to serve more traffic on the radio interface. Radio cells are also getting smaller, so mobile operators can achieve higher level of spatial reuse of the radio channels, too. Besides transmission speed, the quality of the connection is also a very important aspect, which might turn the balance in the competition among operators. The topic of my dissertation is finding the right balance between the quantity and the quality in mobile networks, by focusing on three main aspects: 1.) Tracking mobile user movements in cellular mobile wireless networks, 2.) A Ring based Call Admission Control algorithm and Ring Based Mobility management algorithm, 3.) The performance evaluation of Anycast Based Micro-mobility Management

Security and privacy are among the growing concerns of a Vehicular Ad hoc Network (VANET) which requires a high degree of liability from its participants. In this dissertation, we address security, anonymity, and privacy challenges of VANETs in the light of the IEEE standards for vehicular communications. VANET provides a variety of road-safety and other applications through wireless devices installed in vehicles and roadside infrastructure. However, a vehicle must not be able to take advantage of its anonymity for any misbehavior like sending false messages or malicious updates to other vehicles or a roadside infrastructure. We use proxy signature, identity-based signature, and elliptic curve cryptosystems to provide authentication for infrastructure generated messages, and anonymous authentication for vehicle originated messages. Also, we investigate how some of the MAC-layer weaknesses may impair the security of a VANET. Our solutions are lightweight, bandwidth friendly and compatible to the current standards of vehicular communications.

This book includes a synthesis of some of our previsions research works. It presents firstly a study of interactions between two routing protocols (AODV, DSR) and two transport protocol versions (TCP New Reno, Vegas). After this study, we conduct some simulations to analyze the behavior of these protocols with different node mobility and network load values. The performance results of each protocol are examined to identify our own scenarios in order to evaluate our proposed solution for better interactions between these protocols. This solution is called CL-TCP (Cross Layer TCP). It is an adaptation of the TCP congestion control mechanism with some parameters provided by the routing layer (mobility nodes and the size of routing length). After the evaluation of CL-TCP, the results showed that it significantly improves the interactions between TCP Vegas and AODV protocols.

Comprehensive coverage explaining the correlation and synergy between Next Generation Networks and the existing standardized technologies This book focuses on Next Generation Networks (NGN); in particular, on NGN architectures, protocols and services, including technologies, regulation and business aspects. NGN provides convergence between the traditional telecommunications and the Internet, and it is globally standardized by the ITU (International Telecommunication Union), where ITU is the United Nations specialized agency for Information and Communication Technologies – ICTs. The convergence towards the NGN is based on the Internet technologies, and the introductory chapters cover the Internet fundamentals of today, including architectures, protocols (IPv4, IPv6, TCP, DNS, etc.), Internet services (WWW, e-mail, BitTorrent, Skype, and more), as well as Internet governance. Further, the prerequisite for convergence of all ICT services over single network architectures is broadband access to the Internet. Hence, the book includes architectures of fixed broadband Internet access networks, such as DSL (Digital Subscriber Line) networks, cable networks, FTTH (Fiber To The Home), next generation passive and active optical networks, and metro Ethernet. It also covers network architectures for next generation (4G) mobile and wireless networks (LTE/LTE-Advanced, and Mobile WiMAX 2.0), then Fixed Mobile Convergence – FMC, next generation mobile services, as well as business and regulatory aspects for next generation mobile networks and services. Comprehensive coverage explaining the correlation and synergy between Next Generation Networks and the existing standardized technologies Focuses on Next Generation Networks (NGN) as defined by the ITU, including performance, service architectures and mechanisms, common IMS (IP Multimedia Subsystem), control and signalling protocols used in NGN, security approaches, identity management, NGN Service Overlay Networks, and NGN business models Examines the most important NGN services, including QoS-enabled VoIP, IPTV over NGN, web services in NGN, peer-to-peer services, Ubiquitous Sensor Network (USN) services, VPN services in NGN, Internet of things and web of things Includes the transition towards NGN from the PSTN (Public Switched Telephone Networks) and from the best-effort Internet via the same Internet access Explores advanced topics such as IPv6-based NGN, network virtualization, and future packet based networks, as well as business challenges and opportunities for the NGN evolved networks and services Essential reading for engineers and employees from regulatory bodies, government organisations, telecommunication companies, ICT companies.
