Impact of CBR Traffic on Routing Protocols in MANETs

Mobile ad hoc network is a collection of mobile nodes which are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. This paper examined routing protocols by varying CBR traffic but having identical mobility and stationary environmental conditions for ad hoc network. The simulation results obtained using GloMoSim simulator after comparing different ad hoc routing protocols named AODV, DSR, BFD and WRP based on throughput, collision and byte loss as performance parameters. The detailed simulation results and their analysis is presented. An appropriate and best choice of routing protocol is little difficult situation for some network. As shown in graphs, AODV, DSR routing protocol performs better corresponding to Throughput and Collision performance metrics and BFD algorithm perform slightly better corresponding to Byte Loss performance metrics.
