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.

采用 IEEE 802.11 MAC 的 VANET 的容量、碰撞和干扰

本文分析了 802.11 VANET 的传输容量特性。在此基础上，还研究了 VANET 的碰撞和干扰问题。在 VANET 中应用了概率分析模型。根据概率模型，碰撞/干扰源的数量会影响数据包的收发。针对 VANET 中的多接口路由，提出了一种新方案--一跳一信道。一跳一信道可以有效减少碰撞/干扰源。仿真还证明，一跳一信道的概率更低。因此，一跳一信道的延迟更短。
