Network Simulation Based Parametric Analysis of AODV Protocol for Wireless Mobile Ad-hoc Network

A major aspect of ad-hoc networks is that the nodes can move randomly, which requires the routing protocols. The routing protocol should try to minimize control traffic, such as periodic update messages. Instead the routing protocol should be reactive, thus only calculates routes upon receiving a specific request. The On-demand protocol performs better than the table-driven protocol. The simulator that we are using is Network Simulator (NS-2) which is a most widely used network simulator. It has the capabilities to simulate a range of networks including wired and wireless networks. The size of the network and the offered traffic load affects protocols based on routing, like AODV, to some extent. A large network with many mobile nodes will increase the overhead for AODV quite drastically. This paper is subjected to Adhoc On-demand Distance Vector (AODV) routing protocol and evaluated its performance. Furthermore, in this paper the performance of AODV in terms of packet delivery and routing load is analyzed by varying the number of nodes, parameters through simulation results ns2 simulator.
