Performance Evaluation of Three Mobile Ad-hoc Network Routing Protocols in Different Environments

Mobile ad-hoc wireless networks give us the high probability and high properties to create networks, without any central management or infrastructure, independent and temporary network, that is means wide ubiquitous networks. The intermediate nodes should be able to communicate between them to send and receive the data with ability using at any time and anywhere, the mobility of the intermediate node between the source and destination gives us unstable topology maybe the connection between the nodes will be break often. Therefore, the strategies to design any wireless depend on path routing and protocol selection. In this paper we study and evaluate the effect of mobility on the routing protocols DSDV, AODV and DSR in two different scenarios, the density of nodes and different area in NS2.35 simulation by using three performance metrics in the evaluating the routing protocols are Average Throughput, Packet Delivery Ratio and Average End-to-End Delay.
