MANET is a collection of mobile hosts with wireless network interfaces that form a temporary network without any fixed infrastructure or centralized administration. MANET is infrastructure-less, lack of centralized monitoring and dynamic changing network topology. MANET is highly vulnerable to attack due to open error prone shared wireless medium. In this paper, the authors proposed an algorithm for avoiding and preventing the wormhole attacks in MANET using statistical analysis approach. Simulation results shows that proposed algorithm provides better security and performance in the presence of wormhole attack than conventional AODV.
