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.

Download or read book On the Scalability of Ad Hoc Wireless Networks written by and published by . This book was released on 2008 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation considers the problem of scaling ad hoc wireless networks now being applied to urban mesh and sensor networks scenarios. Ad hoc networks involve multi-hop communication which has inherent scaling problems in that throughput per node drops as the square root of the number of nodes in the network. We investigate mechanisms for improving performance and scalability of multi-hop wireless networks, with focus on system architecture and routing protocol aspects. First we propose a generalized multi-tier hierarchical hybrid network with three tiers of radio nodes: low-power end-user mobile nodes (MN) at the lowest tier, higher power radio forwarding nodes (FN) that support multi-hop routing at intermediate level, and wired access points (AP) at the highest level. We present an analytical model for the capacity of the proposed network and identify conditions on transmission range and node density for scalability to be maintained. From the derived upper and lower bounds, it is shown that the low-tier capacity increases linearly with the number of FN's, and that the high-tier capacity grows linearly with the number of AP's in the scaling region. The analytically obtained capacity results are validated with detailed system simulations for dense network scenarios. The simulation study also examines the allocation of separate channels to avoid the increased protocol overhead which arises in the single channel case. A heuristic distributed channel assignment algorithm is proposed to achieve conflict-free transmissions in the network. Next, we investigate cross-layer adaptive routing as another type of scaling mechanism. An adaptive routing framework, which allows introduction of adjustable parameters and programmable routing modules, is described. The proposed framework can support various cross-layer mechanisms including those based on integrated routing metrics that incorporate PHY and MAC information. We investigate a PHY/MAC aware routing metric (PARMA) which incorporates physical layer link speed and MAC congestion. Design and implementation of PARMA are outlined, and simulation results for typical multi-rate 802.11 ad hoc network scenarios show that PARMA helps improve throughput and decrease congestion by selecting paths with high bit-rate links while avoiding MAC congestion areas.

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.
Download or read book Implementation and Performance Analysis of a Scalable Routing Protocol written by Rudhrakumar Venkatesan and published by . This book was released on 2003 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ad Hoc networks are multi-hop wireless networks consisting of mobile hosts. They do not have any pre-existing network infrastructure and are characterized by constantly changing topology, limited battery power and bandwidth. Typical applications of such networks are battlefield networks, medical relief during natural calamities or disasters, conference room networking, and intra-vehicular communications. Routing packets in an ad-hoc network is a challenge because of the mobile nature of the nodes and the constantly changing topology. In ad hoc networks, each mobile node functions as a router, forwarding packets, establishing routes and helping each other in maintaining the network. A novel scalable routing protocol SLURP (Scalable Location Updated-based Routing Protocol) addresses these issues of ad hoc networks routing. The protocol is based on a location management strategy, which keeps the routing overhead to a minimum. In this thesis we compare the protocol against an existing set of multi-hop ad hoc network routing protocols that cover a range of design choices: DSDV, TORA, DSR, and AODV. We implemented SLURP in the network simulator ns-2, with the necessary wireless extensions. Experiments were run to simulate changes in network topology, number of active sources, link connectivity, and speed of motion. The difference in performance and scalability are illustrated.

Available in PDF, EPUB and Kindle. Book excerpt: 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 sensor networks (WSNs). In WSNs, communication takes place with the help of spatially distributedautonomoussensornodesequippedtosensespeci?cinformation. WSNs, especially the ones that have gained much popularity in the recent years, are, ty- cally, ad hoc in nature and they inherit many characteristics/features of wireless ad hoc networks such as the ability for infrastructure-less setup, minimal or no reliance on network planning, and the ability of the nodes to self-organize and self-con?gure without the involvement of a centralized network manager, router, access point, or a switch. These features help to set up WSNs fast in situations where there is no existing network setup or in times when setting up a ?xed infrastructure network is considered infeasible, for example, in times of emergency or during relief - erations. WSNs ?nd a variety of applications in both the military and the civilian population worldwide such as in cases of enemy intrusion in the battle?eld, object tracking, habitat monitoring, patient monitoring, ?re detection, and so on. Even though sensor networks 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 well-known challenges are attributed to issues relating to coverage and deployment, scalability, quality-of-service, size, computational power, energy ef?ciency, and security.
