Comparative performance analysis of AODV and DSR routing protocols under wormhole attack in mobile ad hoc network on different node's speeds

The Mobile Ad-hoc Network (MANET) is a collection of mobile nodes. These nodes can setup and configured automatically without involvement of user. In MANET each node can move independently. Routing is the main issue because the topology in the MANET changed very fast. Due to power constraint the transmission process is multi hop in nature. Various security attacks can affect the throughput, end-to-end delay, packet delivery ratio of AODV and DSR routing protocols. Wormhole is such type of attack. In wormhole attack the misbehaving node captures the packets from one point and tunnels them to another misbehaving node at another point which replays them locally. In this paper the comparative performance analysis of AODV and DSR routing protocols under wormhole attack in Mobile Ad-Hock network is carried out by changing nodes speed on the basis of average end to end delay and throughput with the help of QualNet 5.0.2 simulator.
