Impact of CBR, FTP Traffic Patterns and Varying node density on Performance of Routing Protocols in MANETs?

An ad hoc network is a collection of wireless mobile nodes forming a temporary network without the use of any preexisting topology, network infrastructure, or centralized administration. Every node in ad hoc network acts as a router, work as hop and forward data packets for other nodes. Routing is the key challenge in mobile ad hoc networks and challenge becomes more difficult and complicated when the type of traffic patterns and size of network changed. The main issue is to compare the existing routing protocol and finding the best one as in the different type of environment and traffic scenarios these protocols gives varying results. The scope of this study is to test routing performance of three different routing protocols (AODV, DSDV, and Dymo) with respect to CBR and FTP traffic pattern. The Random Waypoint mobility model was used for mobility generation. The QualNet 5.0.2 simulator has been used to conduct the simulation. Performance analysis of AODV, DSR and Dymo is evaluated based on Average end to end delay(s), Average Jitters(s), and throughput (bits/s) in Mobile ad hoc networks.
