"Performance Analysis of DSR, AODV Routing Protocols based on Wormhole Attack in Mobile Adhoc Network"

Abstract

ad-hoc network are able work without any existing infrastructure. MANET is a self configure network connected by wireless links. Mobile ad-hoc network uses temporary network which is able to work without any centralize administration or stand alone infrastructure. In mobile ad-hoc network each device move in any direction without any restriction so it changes it links to often with other devices present in same network. Mobility of mobile device anywhere in the network without any centralize administration makes it difficult to manage routing. In mobile ad-hoc network each device need to forward traffic that is not related to its own use and therefore each device work as a router. In this paper we have compared the performance of two On-Demand MANET routing protocol AODV and DSR by using random waypoint mobility model and changing the node density with varying number of source node. DSR and AODV both protocol uses On-Demand route discovery concept but internal mechanism which they use to find the route is significantly different for both protocol. We have analyzed the performance of protocols for low and high node density (50 and 100 nodes) on a 750m*750m area with varying source node and random waypoint mobility model. Simulation with random waypoint mobility model has been carried out by using Qualnet 5.0.2 Simulator. The metrics used for performance evaluation are packet Delivery fraction, Average End-to-End Delay, Average Jitter, and number of packet dropped for buffer overflow.
