Download or read book On Demand Routing in Multi hop Wireless Mobile Ad Hoc Networks written by and published by . This book was released on 2001 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any preexisting network infrastructure or centralized administration. Routing protocols used in ad hoc networks must automatically adjust to environments that can vary between the extremes of high mobility with low bandwidth, and low mobility with high bandwidth. This thesis argues that such protocols must operate in an on-demand fashion and that they must carefully limit the number of nodes required to react to a given topology change in the network. I have embodied these two principles in a routing protocol called Dynamic Source Routing (DSR). As a result of its unique design, the protocol adapts quickly to routing changes when node movement is frequent, yet requires little or no overhead during periods in which nodes move less frequently. By presenting a detailed analysis of DSR's behavior in a variety of situations, this thesis generalizes the lessons learned from DSR so that they can be applied to the many other new routing protocols that have adopted the basic DSR framework. The thesis proves the practicality of the DSR protocol through performance results collected from a full-scale 8 node testbed, and it demonstrates several methodologies for experimenting with protocols and applications in an ad hoc network environment, including the emulation of ad hoc networks.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we explore new techniques for robust, efficient, loop-free on-demand routing in Mobile Ad hoc Networks (MANETs) using the same information (i.e., topology information, sequence numbers, etc.,) used in prior on-demand routing protocol proposals. We provide new insights into the robustness of protocols based on destination-sequence numbers when operating with node failures and loss of routing information, and present a new destination-sequence number framework that works correctly even with failure conditions. We also show how destination-sequence numbers can be manipulated as routing labels for improving performance, rather than being strictly treated as time-stamps. We present two different routing approaches that exploit the topology information that can be collected on-demand during the route request ood search. The first approach translates topology information into labels that are then stored at nodes in strict lexicographic ordering along any successor path to a destination. Loop-freedom is maintained by allowing nodes to only pick "smaller" labels. The second approach maintains a list of topology information that should not be trusted in-addition to the known path to a destination. Using the notion of trusted topology, nodes can always make routingWe conclude our research with a new on-demand routing technique that exploits the route request search process, which is an integral part of any on-demand routing protocol. Without requiring any additional mechanisms or information, we use the uniqueness of route requests to realize a on-demand routing framework. We, then, present extensions to the basic framework to improve performance using more information that can be collected during the flood search process.
Download or read book Adaptive Demand Driven Multicast Routing in Multi Hop Wireless Ad Hoc Networks written by and published by . This book was released on 2004 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ad hoc network does not require any pre-existing infrastructure or configuration but is formed spontaneously by (possibly mobile) nodes that wish to communicate. Each node in the ad hoc network acts as a router and forwards packets on behalf of other nodes, allowing nodes that are not within wireless range of each other to communicate over multi-hop paths. Example ad hoc network applications include disaster relief scenarios, conference attendees who want to form a network in order to exchange documents, friends involved in a distributed outdoors game, surveillance teams composed of persons or robots exploring a dangerous area, or another planet. Previous efforts to design general-purpose on-demand multicast routing protocols for ad hoc networks have utilized periodic (non-on-demand) mechanisms within some portions of the protocol. The overall on-demand nature of such protocols derives from the fact that significant portions of their operation are active only for active multicast groups. However, the periodic mechanisms within the protocol are responsible for core routing functionality and significantly affect overall protocol performance. My thesis in this dissertation is that on-demand multicast that does not rely on periodic techniques is more efficient and performs better than multicast that utilizes such techniques. To support my thesis statement, in this dissertation I present the design and evaluation of a new multicast protocol, the Adaptive Demand-Driven Multicast Routing protocol (ADMR) for multi-hop wireless ad hoc networks. ADMR uses no periodic control packet network-wide floods, periodic neighbor sensing, or periodic routing table exchanges, and adapts its behavior based on network conditions and application sending pattern, allowing efficient detection of broken links and expiration of routing state that is no longer needed.

Available in PDF, EPUB and Kindle. Book excerpt: Ad-hoc wireless networks present a unique design problem for routing. Wireless networks suffer from low bandwidth due to high rates of interference and inherent limitations of the medium. Mobility also increases the bandwidth used for control packets. To conserve on precious bandwidth, routing protocols should generate as few updates as possible. In this dissertation, we propose distance vector solutions to ad-hoc routing because unlike existing routing solutions our solutions do not use sequence numbers and thus are not prone to inefficient or wrong behavior in the presence of node failures. First, we introduce ROAM, the first protocol to correctly tackle the "searching to infinity" problem found in on-demand routing protocols. ROAM can be used in networks with low rates of topology changes because it required reliable updates. Next, we describe two protocols DST (on-demand) and BEST (table-driven) for networks with high rates of topology change. Simulation experiments carried out in two different simulation packages show that these protocols perform an order of magnitude better than representative on-demand and table-driven routing solutions for ad-hoc networks. Finally, we introduce MDST, an on-demand protocol that extends the source tracing algorithm used in DST to create and maintain multiple paths in an ad-hoc wireless network. Multipath routing can be used in ad hoc networks to achieve greater resilience to route failures and better end-to-end delays. Multipath routing is also essential when using QoS metrics like delay in order to avoid route oscillation. We show that multiple paths that are node disjoint and loop free can be maintained with less overhead than DST. Further, these multiple paths decrease the delay of packet delivery and increase the throughput of the network.

This book was released on with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the focus is on the analysis and design of efficient, adaptive, and scalable routing protocols for Mobile Ad Hoc Networks. Next section presents the objective of the work performed in the context of this book. The main objective of this book is to develop routing protocols, which are appropriate for challenging environment of mobile ad-hoc networks. Given the inherent characteristics of these networks, the solutions must be adaptable to dynamic topologies, efficient with the bandwidth usage, scalable and energy efficient when various network parameters are concerned. Moreover, the focus is also on realistic approaches having relevance in real-life deployments. This means that the protocols should not be designed merely based on generic assumptions, which could lead to incorrect conclusions. Network Simulator (ns2.34) is the tools, which are used to determine that the developed algorithms are implementable in real networks. For validation in ad hoc networks, a specific scenario should also be mentioned for which the routing protocol has been designed. Meeting of these objectives includes providing the perception of the realities of ad-hoc networking. In addition, the proposed solutions should be compared against corresponding solutions found in the literature. New solutions must offer better performance with respect to others, to be able to contribute something to the research community. To summarize, the main goal of this book is to improve the knowledge in ad-hoc networking by providing solutions, which can help in developing new features for MANETs. This book will give the details of the methodology employed to achieve the goals.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, routing protocols, load-balancing protocols, and efficient evaluation techniques for multi-hop mobile wireless networks are explored. With the advancements made in wireless communication and computer technologies, a new type of mobile wireless network, known as a mobile ad hoc network (MANET), has drawn constant attention. In recent years, several routing protocols for MANETs have been proposed. However, there still remains the need for mechanisms for better scalability support with respect to network size, traffic volume, and mobility. To address this issue, a new method for multi-hop routing in MANETs called Dynamic NIx-Vector Routing (DNVR) is proposed. DNVR has several distinct features compared to other existing on-demand routing protocols, which lead to more stable routes and better scalability. Currently, ad hoc routing protocols lack load-balancing capabilities. Therefore they often fail to provide good service quality, especially in the presence of a large volume of network traffic since the network load concentrates on some nodes, resulting in a highly congested environment. To address this issue, a novel load-balancing technique for ad hoc on-demand routing protocols is proposed. The new method is simple but very effective in achieving load balance and congestion alleviation. In addition, it operates in a completely distributed fashion. To evaluate and verify wireless network protocols effectively, especially to test their scalability properties, scalable and efficient network simulation methods are required. Usually simulation of such large-scale wireless networks needs a long execution time and requires a large amount of computing resources such as powerful CPUs and memory. Traditionally, to cope with this problem, parallel network simulation techniques with parallel computing capabilities have been considered. This dissertation explores a different type of method, which is efficient and can be achieved with a sequential simulation, as well as a parallel and distributed technique for large-scale mobile wireless networks.
