Capacity, Collision and Interference of VANET with IEEE 802.11 MAC

Abstract

In this paper, we analyze the transport capacity characteristic of VANET in 802.11. Based on these, the collision and interference of VANET are also studied. A probability analysis model is applied in VANET. The number of collision/interference source impacted packets transmission-receive according to the probability model. A new scheme -one hop one channel, is proposed for multi-interface routing in VANET. One hop one channel can reduce collision/interference source efficiently. The simulation also proved that the probability of one hop one channel is lower. As it is, delay of one hop one channel is shorter.
