Book Description

This book provides about Mobile Ad-hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any pre-existing infrastructure in which each node can act as a router. One of the main challenges of MANET is the design of robust routing algorithms that adapt to the frequent and randomly changing network topology. A variety of routing protocols have been proposed and several of them have been extensively simulated or implemented as well. In this book, we compare and evaluate the performance of two types of on demand routing protocols- Ad-hoc On-demand Distance Vector (AODV) routing protocol, which is unipath and Adhoc On-demand Multipath Distance Vector (AOMDV) routing protocol. In this paper we note that on comparing the performance of AODV and AOMDV, AOMDV incurs more routing overhead and packet delay than AODV but it had a better efficiency when it comes to number of packets dropped and packet delivery. This also describes how to use the PUMA for sending message in the routing applications and to give maximum efficiency.

Book Description

This book gives a comprehensive overview of the challenges and possible solutions in Mobile Adhoc Networks with particular reference to Routing and other network topologies in order to improve the efficiency. When a routing protocol for MANET Networks (mobile and ad hoc networks) does a route discovery, it does not discover the shortest route but the route through which the route request flood traveled faster. In addition, since nodes are moving, a route that was the shortest one at discovery time might stop being so in quite a short period of time. This causes, not only a much bigger end-to-end delay, but also more collisions and faster power consumption. In order to avoid all the performance loss due to these problems, this paper develops a technique to periodically discover shortcuts to the active routes that can be used with any destination vector routing protocol. It also shows how the same mechanism can be used as a bidirectional route recovery mechanism. We consider the problem of incorporating security mechanisms into routing protocols for ad hoc networks. Canned security solutions like IPSec are not applicable. We look at AODV in detail and develop a security mechanism to protect its routing information. We also briefly discuss whether our techniques would also be applicable to other similar routing protocols and about how a key management scheme could be used in conjunction with the solution that we provide.

Book Description

Master's Thesis from the year 2012 in the subject Computer Science - Software, Coventry University (MSRSAS - computer science and networking), course: Design and Implementation of the Extended Routing Information Protocol[ERIP] for Mobile Ad-hoc Networks in Linux, language: English, abstract: A Mobile Ad-hoc Network (MANET) is a network that can be established with no fixed infrastructure. This means that all its nodes behave as routers and take part in its discovery and maintenance of routes to other nodes in the network. Its routing protocol has to be able to cope with the new challenges that a MANET creates such as node mobility, security maintenance, quality of service, limited bandwidth and limited power supply. These challenges set new demands on MANET routing protocols, like low overhead operation, routing security and best path selection. This Thesis deals with the design and implementation of the Extended Routing Information Protocol (ERIP) for mobile ad-hoc networks in Linux. ERIP is a proactive protocol, characterized by low overhead operation, best path selection based on hop count, loop free working and routing security. Raw sockets are used for exchange of routing information, whereas data exchange happens via TCP or UDP sockets as required by the application. Low overhead operation of ERIP is guaranteed by using the incremental dump strategy. Incremental dumping of the routing table is realized by scheduling only partial updates, instead of full. The routing table is encrypted before broadcast using a simple shared key algorithm to provide routing security. The routing functionality of the implemented protocol is tested by first running ERIP on two laptops and using VLC media player to stream multimedia data between the laptops. The two laptops were then moved out of range of each other and intermediate nodes (laptops) were brought in that were running the same routing protocol. The data was communicated over multiple hops in near real time. The best path selection property was proved by setting up a network of ERIP nodes that had multiple paths between source and destination with different hop counts. The implemented protocol consistently routed data through the path that had the least hop count. Porting the developed protocol to the Linux kernel would allow it be part of the standard Linux distribution. Also, more complex cryptography algorithms can be implemented to provide data and routing security.

Book Description

Overview and Goals Wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless mesh networks (WMNs). The attractiveness of WMNs, in general, is attributed to their characteristics such as the ability to dynamically self-organize and self-con?gure, coupled with the ability to maintain mesh connectivity leading, in effect, to low set-up/installation costs, simpler maintenance tasks, and service coverage with high reliability and fault-tolerance. WMNs also support their integration with existing wireless networks such as cellular networks, WLANs, wireless-?delity (Wi-Fi), and worldwide interoperability of microwave access (WiMAX). WMNs have found u- ful applications in a broad range of domains such as broadband home networking, commercial/business networking, and community networking – particularly attr- tive in offering broadband wireless access with low initial installation and set-up costs. Even though WMNs have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the wellknownchallenges areattributedtoissuesrelatingtoscalability(signi?cantdrop in throughput with the increase in the number of nodes), multicasting, offering qu- ity of service guarantees, energy ef?ciency, and security. This handbook attempts to provide a comprehensive guide on fundamental key topics coupled with new ideas and results in the areas of WMNs. The book has been prepared keeping in mind that it needs to prove itself to be a valuable resource dealing with both the important core and the specialized issues in WMNs.

Book Description

In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.
