Abstract

This paper presents a vehicular ad hoc network routing protocol with link expiration time (VARP-LET) that uses LET information in the creation of routes. The proposed protocol uses LET information to increase the reliability and stability of the routes. In addition to LET, a route break indicator (RBI) message is used to reduce the packet loss. The effective use of LET and RBI is tested in simulated network environment using NS-2. The simulation results show that VARP-LET protocol increases packet delivery ratio by 20.7% in Manhattan mobility model and by 30% in highway mobility scenario compared to the traditional AODV protocol. It is also shown that the protocol significantly reduces frequent route failure and routing overhead.
