Simulation and Performance Analysis of Aodv Protocol in Manet

The Mobile Ad-hoc Networks (MANETs) is an network consisting of wireless mobile nodes without any pre-existing infrastructure or the aid of any centralized administration. MANET is a self configuring network and the topology of the network is dynamic or keeps on changing as the nodes move randomly. MANET is a collection of mobile nodes that move randomly. There are many protocols for such networks. One such protocol is Ad-hoc On Demand Distance Vector (AODV) routing protocol. Among all other protocols AODV is preferred because it minimizes the routing overhead and hence enhance the performance of the network. We have presented a simulation study which shows that Enhanced AODV works better then basic AODV when malicious node found. we have shown the performance of AODV protocol for the parameter, packet delivery ratio and packet loss ratio. As we increase the number of nodes for performing the simulation of AODV routing protocol, number of sent, routing and delivered packets changes hence the performance parameters changes.
