A performance analysis of AODV and DSR routing protocolsin mobile wireless networks

A performance analysis of ad-hoc on demand distance vector (AODV) and dynamic source routing (DSR) protocols in mobile wireless networks was carried out. This was achieved by measuring average end-to-end delay, jitter, normalised routing load, packet delivery fraction, and hop count. The experiments were based on 1 to 10 source(s) continuously sending packets (CBR over UDP) at a rate of 64 kbps for IP telephony and 192 kbps for video on demand to 1 to 10 destination(s). The nodes moved at an average speed of 6.11m/s, the pause time was increased from 0s (representing high mobility) to 900s (representing no mobility) for each set-up and the simulation time was 900 sec. The study indicated that AODV has smaller average end-to-end delay and jitter for both the audio and video applications, and for all mobility values considered. DSR on the other hand, has smaller normalised routing load indicating smaller routing packet overhead. This was the case for both the audio and video applications as well as with different mobilities. Packet delivery fraction decreased for both routing protocols as the number of node was increased, indicating an increase in packet loss.
