Auto-Configuration Protocols in Mobile Ad Hoc Networks  [PDF]

Abstract: The TCP/IP protocol allows the different nodes in a network to communicate by associating a different IP address to each node. In wired or wireless networks with infrastructure, we have a server or node acting as such which correctly assigns IP addresses, but in mobile ad hoc networks there is no such centralized entity capable of carrying out this function. Therefore, a protocol is needed to perform the network configuration automatically and in a dynamic way, which will use all nodes in the network (or part thereof) as if they were servers that manage IP addresses. This article reviews the major proposed auto-configuration protocols for mobile ad hoc networks, with particular emphasis on one of the most recent: D2HCP. This work also includes a comparison of auto-configuration protocols for mobile ad hoc networks by specifying the most relevant metrics, such as a guarantee of uniqueness, overhead, latency, dependency on the routing protocol and uniformity.
Secure Route Path Formation in Ad hoc On-demand Distance Vector Routing Protocol  [PDF]
Muhammad Asfand-e-Yar,Muhammad Sher
Information Technology Journal , 2004,
Abstract: This study describes the secure route path formation in the Ad hoc On-demand Distance Vector routing protocol. For secure route path formation in Ad hoc On-demand Distance Vector Routing Protocol (RSA) for encryption is used. The Secure Ad hoc On-demand Distance Vector (SAODV) is an extension in Ad hoc On-demand Distance Vector routing protocol that is used to protect the route path from integrity and authentication attacks. Ad hoc network maintains a routing table giving distance from itself to all possible destinations. In Ad hoc On-demand Distance Vector routing protocol the route discovery is done by route request and reply packets. After establishing a route the communication between source and destination takes place. Ad hoc On-demand Distance Vector routing protocol solves the loop formation. It works on wired as well as on wireless networks.

Abstract: In wireless Ad hoc networks, multi-path routing is an important routing algorithm. The aim of using multi-path routing is to get more throughputs. The analysis shows that under multi-path routing, the throughput from source node to destination node has little to do with their distance; under single-path routing, the throughputs from source node to destination node decrease quickly with the increase of their hops of path length.

Abstract: Mobile ad hoc network (MANET) is a set of wireless mobile computer forming a temporary network with out any wired infrastructure, due to dynamic nature of topology and other constraints transmission routing is a challenging task in MANET. k path splittable routing establish at most k paths between single source and single destination node, this scheme provides better load balancing and increase in reliability of data transmission. This paper presents a comparative study of single path routing and k path routing in mobile ad hoc network
Constructing Path Efficient and Energy Aware Virtual Multicast Backbones in Static Ad Hoc Wireless Networks

International Journal of Wireless & Mobile Networks , 2010,
Abstract: For stationary wireless ad hoc networks, one of the key challenging issues in routing and multicasting isto conserve as much energy as possible without compromising path efficiency measured as end-to-enddelay. In this paper, we address the problem of path efficient and energy aware multicasting in staticwireless ad hoc networks. We propose a novel distributed scalable algorithm for finding a virtualmulticast backbone (VMB). Based on this VMB, we have further developed a multicasting scheme thatjointly improves path efficiency and energy conservation. By exploiting inherent broadcast advantage ofwireless communication and employing a more realistic energy consumption model for wirelesscommunication which not only depends on radio propagation losses but also on energy losses intransceiver circuitry, our simulation results show that the proposed VMB-based multicasting schemeoutperforms existing prominent tree based energy conserving, path efficient multicasting schemes.
Path Selection Based Route Finding Protocol in Mobile Ad Hoc Network

Asian Journal of Information Technology , 2012,
Abstract: Mobile Ad Hoc Network (MANET) is an autonomous system of functionally equivalent mobile nodes, which must be able to communicate while moving, without any kind of wired infrastructure. In such an environment, it may be necessary for one mobile host to enlist the aid of other hosts in forwarding a packet to its destination, due to the limited range of each mobile host s wireless transmissions. To this end, mobile nodes must cooperate to provide the routing service. Routing in mobile environment is challenging due to the constraints existing on the resources (transmission bandwidth CPU time and battery power) and the required ability of the protocol to effectively track topological changes. Limited bandwidth and a high degree of mobility require that routing protocols for ad hoc networks be robust, simple and energy conserving. Efficient, dynamic routing is also one of the key challenges in this network. In recent past, this problem has been addressed by several research efforts, resulting in a large body of literature. Each node participating in the network acts both as host and a router and must therefore be willing to forward packets for other nodes. For this purpose, a number of routing protocols like Dynamic Source Routing (DSR) Protocol, Ad Hoc On-Demand Distance Vector (AODV) Routing, Destination Sequenced Distance Vector (DSDV) and Temporally Ordered Routing Algorithm (TORA) have been implemented. This study presents a new on demand protocol for routing in ad hoc networks that selects a route of smallest hop count and consisting of nodes in a non-existing path. Our protocol adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods in which hosts move less frequently. The path selection method used in this protocol always prefers to a route with more non-forwarding nodes and provides the solution to cope with network mobility by selecting route efficiently. Our route finding protocol provides loop free routes even while able to repair broken links. Because the protocol does not require global periodic routing advertisements the demand on the overall bandwidth available to the mobile nodes is substantially less than in those protocols that require such advertisements. Nevertheless, we can still maintain most of the advantages of basic Distance vector routing mechanisms. Our algorithm scales to large populations of mobile nodes wishing to form ad-hoc networks. We also point out future research issues in the context of individual routing approaches as well as from the overall system perspective.

Emergency Video Multi-Path Transfer over Ad Hoc Wireless Networks  [cached]

Journal of Communications , 2009, DOI: 10.4304/jcm.4.5.329-338
Abstract: Ad Hoc networks utilize multi-hop radio relay without the need for a base station, supporting mobility and allowing them to be quickly deployed in an emergency. Real-time video communication across an ad hoc network allows helpers to better understand the nature of the problem within a disaster area but the lack of centralized routing and network resource management is challenging, particularly if the wireless nodes have limited processing power. Multi-path solutions have been proposed for video transfer. This paper investigates two practical schemes, Video Redundancy Coding and a proposal of the paper, H.264 codec redundant frames. The paper reports that redundant frames when used in combination with multipath do result in as much as 10 dB improvement in delivered video quality, making the difference between acceptable and unacceptable visual communication in a disaster scenario.
