An Improved DSDV Routing Protocol for Wireless Ad Hoc Networks

Abstract

A Mobile Ad hoc NETwork (MANET) is a kind of wireless ad-hoc network and is a self configuring network of mobile routers connected by wireless links. The wireless links form the union of an arbitrary topology. There are various routing protocols available for MANETs. The most popular ones are DSR, AODV and DSDV. This paper examines routing protocol for mobile ad hoc networks– the Destination Sequenced Distance Vector (DSDV) and On –Demand protocol that evaluates both protocols based on the packet delivery fraction and average delay while varying number of sources and pause time. In this paper we consider the new approach an Improved-DSDV Protocol is proposed for Ad Hoc networks. Improved -DSDV overcomes the problem of stale routes, and thereby improves the performance of regular DSDV. The proposed protocol has been implemented in the NS-2 Simulator and performance comparison has been made with regular DSDV and improved DSDV protocols. We compare the performance of our work with DSDV. In our improved DSDV routing protocol, nodes can cooperate together to obtain an objective opinion about another node's trustworthiness. The performance metrics considered are packet-delivery ratio.
