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.

Download or read book On demand Loop Free Routing in Ad Hoc Networks Using Source Sequence Numbers written by and published by . This book was released on 2005 with total page 11 pages. 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).
Download or read book Routing in the Internet Using Partial Link State Information written by Marcelo Spohn and published by . This book was released on 2001 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on routing in wired and wireless segments of the Internet using partial link-state information. Although efficient algorithms have been proposed based on both link-state and distance-vector information, link-state routing is more efficient than distance-vector routing when constraints are placed on the paths offered to destinations, which is the case for QoS routing offering paths with required delay, bandwidth, reliability, cost, or other parameters. We present a new link-state routing protocol for wired internetworks called ALP (adaptive link-state protocol). In ALP, a router sends updates to its neighbors regarding the links in its preferred paths to destinations. Each router decides which links to report to its neighbors based on its local computation of preferred paths. A router running ALP does not ask its neighbors to delete links; instead, a router simply updates its neighbors with the most recent information about those links it decides to take out of its preferred paths. We introduce and analyze two routing algorithms for wireless networks: the source- tree adaptive routing (STAR) protocol, and the neighborhood-aware source routing (NSR) protocol. STAR is the first example of a table-driven routing protocol that is more efficient than prior table-driven and on-demand routing protocols by exploiting link-state information to allow paths taken to destinations to deviate from the optimum in order to save bandwidth without creating loops. NSR is an on-demand routing protocol based on partial topology information and source routing. STAR is shown to be more efficient than the dynamic source routing (DSR) protocol in small ad hoc networks, and NSR is shown to outperform STAR and DSR in large wireless networks with mobile nodes.
Download or read book Ad Hoc and Sensor Networks written by Carlos de Morais Cordeiro and published by World Scientific. This book was released on 2011 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive yet easy coverage of ad hoc and sensor networks and fills the gap of existing literature in this growing field. It emphasizes that there is a major interdependence among various layers of the network protocol stack. Contrary to wired or even one-hop cellular networks, the lack of a fixed infrastructure, the inherent mobility, the wireless channel, and the underlying routing mechanism by ad hoc and sensor networks introduce a number of technological challenges that are difficult to address within the boundaries of a single protocol layer. All existing textbooks on the subject often focus on a specific aspect of the technology, and fail to provide critical insights on cross-layer interdependencies. To fully understand these intriguing networks, one need to grasp specific solutions individually, and also the many interdependencies and cross-layer interactions.

Download or read book Using Minimal Source Trees for On Demand Routing in Ad Hoc Networks written by and published by . This book was released on 2001 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The on-demand routing protocols that have been proposed to date use either path information (e.g., DSR) or distance information (e.g., AODV). We present SOAR, an on-demand link-state protocol based on partial link-state information in which a wireless router communicates to its neighbors the link states of only those links in its source tree that belong to the paths it chooses to advertise for reaching destinations with which it has active flows. SOAR does not require periodic link-state advertisements when there are no link connectivity changes in the network. Simulation studies for several scenarios of node mobility and traffic flows reveal that SOAR performs more efficiently than DSR, which is one of the best performing on-demand routing approaches based on path information.

This book was released on 2014-08-12 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (postgraduate) from the year 2014 in the subject Computer Science - Internet, New Technologies, , language: English, abstract: Ad-hoc network is a concept in computer communications, which means that users wanting to communicate with each other from a temporary network, without any form of centralized administration. Each node participating in the network acts both as host and router and must therefore be willing to forward packets for other nodes. For this purpose, a routing protocol is needed. Routing protocols in MANET such as OLSR-INRIA, DSR and ZRP finds out the path between a given sources destination node pair without considering the reliability of the links in the selected path. Some links in MANET are unreliable due to interference from transmissions from adjacent links, ambient noise system noise, jamming signals from intruder nodes all of which results in low throughput, packet delivery ratio, high jitter and end-to-end delay. In our work, we use Signal-to-Noise Ratio (SNR) as a measure of the link reliability. We propose modified secure version of the of three protocols namely OLSR-INRIA, DSR & ZRP coined as SOLSR-INRIA , SDSR, & SZRP which takes into account the link SNR value as a measure of link reliability in addition to the other parameters as in the original method in the route discovery phase. QualNet network simulator have been extensively used to evaluate the performance of our modified secure routing protocol over two different network scenarios consisting of 52 and 72 mobile nodes respectively considering random waypoint (RWP) mobility model. The results indicate high throughput, high packet delivery ratio and low jitter and end-to-end delay in comparison to the original protocols which do not account for wireless links reliability.
