Performance evaluation of routing protocol on AODV and DSR under wormhole attack

Today’s Mobile Ad hoc Networks (MANETs) became a popular issue for scientists, and diverse studies have been made to increase the performance of ad hoc networks. In MANET nodes compromise to forward packets for each other communicate beyond their transmission range. The mobile nodes communicate with each other without any infrastructure. As wireless ad-hoc networks lack an infrastructure, they are exposed to a lot of attacks [1]. One of these attacks called Wormhole Attack that two adversary node collaborate together to transmit the packets in out of band channel. In this paper, performance of Ad hoc on-Demand Distance Vector (AODV) Protocol and Dynamic Source Routing (DSR) protocol are evaluated in presence of wormhole attack and without wormhole attack with Constant Bit Rate (CBR) traffic under dissimilar scalable network mobility. Also we evaluate effect and compare it with standard protocol in term of Packet Delivery Ratio, throughput and End to End Delay via simulation, using Network Simulation2 (NS2) for our research.
