Performance evaluation of beaconing in dense VANETs

Beaconing is one of the core communication method for Vehicle Ad Hoc Networks (VANETs). In this paper we traced the beaconing behavior in dense VANETs by NS2 with free space, two-ray ground, and shadowing radio propagation models. Among the 100 line up vehicles with 10m inter-vehicle distance, one beacon can be successfully received by all vehicles in 55ms, the packet loss rate is about 40%. We also observed that there is fluctuation behavior in packet receive.
