Analytical Study and Performance Comparison of various Routing Protocols

A wireless ad-hoc network is a collection of mobile nodes that makes a multi hop autonomous system without any fixed infrastructure. The nodes use service of other nodes in the network to transmit packet to the destination nodes. This paper contain the study of three MANET routing protocol given by various researchers. In this paper, we have also studies the comparison of the performance of the DSR, AODV, and OLSR routing protocols. We have analyzed the performance of protocols in different traffic load including end to end delay, throughput, and video packet delay variation and routing traffic overhead. A Simulation result shows that in the case of file transfer with TCP connection, OLSR acts better in terms of end to end delay and upload response time, but with high routing overhead. In the case of the video transfer with UDP connection, AODV acts better in terms of throughput, delay variation, end to end delay and have low routing traffic.
