Performance Evaluation of Routing Protocols in MANETs Under Wormhole Attack
Mobile Ad-Hoc Network is a group of wireless mobile nodes connected to each-other without any central administrator. Nodes can move from one place to another in the network or may leave or join the network at any time. Due to this the topology of the network changes rapidly. So the routing protocols are required that can adopt the frequent changes in the network topology. Due to the absence of central administrator the MANETs are vulnerable to attacks. In this paper comparison of reactive protocols i.e., AODV and DYMO has been done under three types of wormhole attack. Performance is measured with metrics like Packet Delivery Ratio, Average End-to-End Delay, Throughput and Jitter by varying the number of nodes.
