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: We based TARP on the basic idea of neighborhood trust where the trust-level of a node is based on its reputation among its neighbors. FL has been perceived to be an excellent choice for many trust control system applications since it mimics human control logic. Tuning the system can be done by changing the rule antecedents or conclusions, changing the centers of the input and/or output membership functions.

Download or read book Medium Access and Routing in Multi Hop Wireless Infrastructures written by Ayman Wazwaz and published by LAP Lambert Academic Publishing. This book was released on 2011-08 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi hop wireless infrastructures can be used as an extension to fixed infrastructures, where wireless nodes form a large network that provides access to the fixed network infrastructure, such as the internet, via multiple wireless hops. Wireless LANs and routing techniques, used in ad hoc networks, can be used in such a network. In this work, we use the IEEE 802.11 standard, extended with power control to optimize the performance of such a network. This work focuses on the Medium Access Control (MAC) mechanism, through Carrier Sense Multiple Accesses with Collision Avoidance (CSMA/CA). By limiting the transmission power to the level just sufficient for correct reception at the receiver, the network is able to have multiple transmissions performed simultaneously, and reduces the interference between transmitting nodes. We propose a routing algorithm that uses paths as efficient as possible in terms of power, interference level and number of hops. Validation of some of the proposed mechanisms has been done with the OPNET modeler simulator, using different models for path loss, traffic distributions, and topologies. The results show higher performance when using power control.

Download or read book Routing with Cooperative Transmissions in Wireless Ad Hoc Networks written by Aylin Aksu and published by LAP Lambert Academic Publishing. This book was released on 2009-09 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cooperative transmissions emulating multi-antenna systems may help reduce the total energy consumption in wireless networks. In this book, we define a virtual Multiple-Input Single-Output (vMISO) link to be established when a group of transmitters jointly enable space-time communications with a single receiver. We present a novel approach in characterizing the optimal multi-hop vMISO routing in ad hoc networks. The key advantages of vMISO links are the increase in transmission range and the decrease in the required transmission energy due to diversity gain. Specifically, we solve a nonlinear program that minimizes the total energy cost of reliable end-to-end transmissions by selecting the optimal cooperation set. Our results indicate that a multi-hop vMISO system is energy efficient only when a few nodes cooperate at each hop. We design a new greedy geographical vMISO routing protocol. Also, we formulate the network lifetime maximization with vMISO routing as a nonlinear program. Then, we present a novel cooperation set selection and flow augmentation based routing heuristic that can significantly increase the network lifetime compared to Single-Input Single-Output systems.
Download or read book Resource Management in Multi hop Ad Hoc Networks written by David A. Maltz and published by . This book was released on 1999 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Routing protocols have been developed that allow such nodes to communicate, but these protocols typically provide only best-effort service. In particular, they do not provide a way to control the consumption of resources in the network, such as the battery power or the carrying capacity of the nodes. This proposal describes a scheme of path-state and flow-state mechanisms that can used [sic] to explicitly manage resources in an ad hoc network, explains how the scheme can be evaluated, and argues for its importance."
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.
