Performance Evaluation of MANET Routing Protocols under Different Traffic Loads for Varying Maximum Congestion Window Size

Abstract

A Mobile ad hoc network is a collection of wireless mobile nodes connected to form a temporary wireless network without using any communication infrastructure. Due to limited network resources and in order to exchange data packets within the network, wireless multiple hops route scheme adopted for mobile node’s connection. Researchers, with the increasing importance of applications in nonmilitary areas proposed several routing protocols for mobile ad hoc networks. This work investigates and compares the performance of MANET routing protocols, namely AODV, DSR and DSDV under different traffic loads with different maximum TCP congestion window size. The Metrics used to compare routing protocol performance are addressed as a packet delivery ratio, the average end-to-end delay, average routing load, and average network throughput.
