The Effect of Velocity and Unresponsive Traffic Volume on Performance of Routing Protocols in MANET

Mobile ad hoc networks (MANETs) form a random network by consists of mobile nodes where node share information with each other while moving. Due to presence of mobility in the MANET, the interconnections between nodes are likely to change, resulting in frequent changes of network topology. Therefore there is a need of identifying efficient dynamic routing protocol to provide call services in such network. In this paper, the effect of node velocity and unresponsive traffic volume is explored on performance of three routing protocols i.e. DSR, AODV and DYMO via NS2 simulator of ad hoc network of 100 mobile nodes. The performance is measured based on traffic admission ratio, packet delivery ratio (PDR), routing overhead, and average end-to-end delay. We observe that DYMO performs better in terms of PDR and traffic admission ratio and DSR has least overhead than others irrespective of node velocity, traffic volume and number of connection.
