Impact of Pause Time on the Performance of DSR, LAR1 and FSR Routing Protocols in Wireless Ad hoc Network?

The performance analysis of the protocols is the most important step prior to selecting a meticulous protocol. In this paper, the performance of Dynamic Source Routing (DSR), Location-Aided Routing1 (LAR1) and Fisheye State Routing (FSR) protocols using Qualnet 5.0.2 simulator have been evaluated. The performance of above routing protocols has been evaluated on the basis average jitter, average end-to-end delay and throughput metrics. The simulation results show that average jitter, and average end-to-end delay is less in DSR protocol as compared to LAR1 protocol and FSR protocol. The throughput of FSR protocol is better in comparison of DSR protocol and LAR1 protocol. At the same time average jitter and end to end delay is less in LAR1 protocol as compared to FSR protocol. However throughput of LAR1 protocol is higher than that of DSR protocol.
