Abstract

The creation of highly reliable routing protocol for wireless vehicular ad hoc networking (VANET) presents a real challenge to the wireless community. Recently, a Bypass-AODV [1] mechanism is proposed to enhance the performance of standard AODV by overcoming several inherited problems such as a newly non-optimal reconstructed route, out-of-order delivery, packet drops, and routing overhead increase. In this work, the impact of mobility on Bypass-AODV is investigated assuming a random way-point model for node mobility. The Bypass-AODV along with original AODV, DSR and TORA are evaluated using NS-2 for TCP traffic with multiple connections under a wide range of node speed. The simulation results show that Bypass-AODV outperforms all other on-demand routing protocols under consideration whether for short connections or long connections. More, the results show an interesting feature that is the insensitivity of Bypass-AODV goodput to the change in mobile speed. This feature makes the proposed routing protocol very attractive to VANET applications.
