摘要：AbstractIEEE 802.11p is an improved edition of the IEEE 802.11 protocol which serves specifically for vehicle to infrastructure (V2I) communication. It can realize a fast V2I wireless communication connection in the urban road environment and ensure transportation safety and communication reliability for moving vehicles. However, the effectiveness and reliability for vehicle wireless access based on IEEE 802.11p in the highway environment still need to be verified even if this protocol could work in the complicated urban road condition. In this paper, an IEEE 802.11p based V2I wireless communication simulation system in the highway environment is built by NS-2 simulation, and several key indices that reflect the system performance including average transfer delay, packet loss rate and throughput are analyzed.
