Performance Evaluation of Wormhole and Sybil Attacks in AODV

The Mobile Ad hoc Networks (MANETs) is a collection of wireless nodes which interact with each other by
sending packets to one another or on behalf of another node, with the absence of any central network infrastructure to
control data routing. The nodes cooperatively forward data packets to other nodes in network by using the routing
protocol. These routing protocols are, however,insecure, thus, the MANET becomes open to malicious attacks. Some
malicious attack s commonly observed in MANET environment are wormhole and Sybil attacks. The objective of this work
is to analyze the performance parameters of throughput, delay and packet loss in AODV with the existence of such
attacks. It has been observed from simulation results that the performance parameters are affected very much when there
is an attack due to wormholes and Sybil.
