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.

Available in PDF, EPUB and Kindle. Book excerpt: In any on-demand routing protocol, sources flood route requests (RREQ) to build routes to destinations, and each new RREQ is identified uniquely with a source-sequenced label (SSL) consisting of the source identifier and a locally generated sequence number. As a RREQ propagates, it creates a directed acyclic graph (DAG), because nodes relay each RREQ only once. We present the first framework for loop-free on-demand routing in ad hoc networks that is based directly on SSLs, rather than on independent mechanisms, which has been the way in which prior on-demand routing protocols have been designed. Extensive simulation results for simple protocol instantiations of our new framework operating in scenarios with 50 and 100-nodes under different traffic patterns show that our new protocols outperform AODV (Ad hoc On Demand Distance Vector), DSR (Dynamic Source Routing), and OLSR (Optimized Link State Routing).

Available in PDF, EPUB and Kindle. Book excerpt: A new protocol is presented for on-demand loop-free routing in ad hoc networks. The new protocol called labeled distance routing (LDR) protocol uses a distance invariant to establish all ordering criterion and per-destination sequence numbers to reset the invariant resulting in loop-freedom at every instant. The distance invariant allows nodes to change their next hops or distances to destinations without creating routing-table loops. The destination sequence number which only the destination may increment permits nodes to reset the values of their distance invariants. The performance of LDR is compared against the performance of three other protocols that are representative of the state-of-the-art namely AODV, DSR, and OLSR.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been many developments in communication technology. This has greatly enhanced the computing power of small handheld resource-constrained mobile devices. Different generations of communication technology have evolved. This had led to new research for communication of large volumes of data in different transmission media and the design of different communication protocols. Another direction of research concerns the secure and error-free communication between the sender and receiver despite the risk of the presence of an eavesdropper. For the communication requirement of a huge amount of multimedia streaming data, a lot of research has been carried out in the design of proper overlay networks. The book addresses new research techniques that have evolved to handle these challenges.

Download or read book On demand Link state Routing in Ad hoc Networks written by Soumya Roy and published by . This book was released on 2003 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores the challenges, merits and demerits of using link-state information for on-demand routing in ad hoc networks, such that routers maintain path information for only those destinations for which they have data traffic. We first present the source tree on-demand adaptive routing (SOAR) protocol, in which each router exchanges with its neighbors a "source tree" containing paths to only those destinations for which the router is the source or relay of data packets. The main advantage of SOAR is that it is more scalable and better performing than current state-of-the-art on-demand routing protocols. However, a limitation of SOAR is that it requires data packets to specify the paths they traverse to detect loops. To eliminate the need for source routing or path traversal information in data packets, we introduce the on-demand link-vector (OLIVE) protocol, which prevents temporary loops for each destination by synchronizing relevant link-state information among neighbors. In OLIVE, the advertised paths combine to form a source graph, rather than a source tree. OLIVE is shown to outperform the current routing protocols proposed for mobile ad-hoc networks in terms of control overhead, throughput and network delay.
