In today’s life wireless networks are much easier to use rather than wired network. As wireless network is having more mobility and scalability it is used every now and then. Mobile Ad-hoc Networks(MANETs) is a collection of self-organized mobile devices forming a temporary network without any central infrastructure. In such network, nodes must co-operate with each other so as to extend their transmission range and transfer data from one part of the network to another one. The AODV protocol is an on-demand routing protocol which initiates a route discovery process only when there is data to be transmitted, to reduce the number of broadcast messages forwarded throughout the network. The different malicious attacks prevailing in the systems are such as black hole, gray hole, worm hole. But there is a certain drawback in MANETs, that it becomes prone to malicious attacks very fast. To avoid such attacks a good intrusion detection and prevention system is needed. Study and comparative simulation analysis of various malicious attacks, their detection and prevention algorithms in AODV(Ad-hoc On Demand distance Vector)will be carried out using MATLAB/NETWORK SIMULATOR(NS).
