Abstract

Routing in vehicular ad hoc networks (VANETs) is one of the challenging issues that has received more attention in recent literature. Research results show that contention-based forwarding protocols are more scalable and more resilient to high mobility of vehicles and rapid topology changes compared with topology-based and position-based routing protocols. In such forwarding protocols, the best next-hop node is elected based on a contention timer value that is assigned to each next-hop candidate. The design of an efficient contention timer function is an important part of such forwarding protocols. In this paper, first we introduce a new contention timer function based on two criteria that take greediness and link stability into account, greediness for selecting the shortest path and link stability for reducing communications over lossy links. Then we apply the contention timer function to an existing contention-based forwarding algorithm to make it mobility-aware. The optimized algorithm is referred to as MACBF algorithm. Simulation results show that MACBF can improve packet delivery ratio, average end-to-end delay and routing overhead in highly mobile highway scenarios.
