摘要 在研究IEEE802.11DCF的基础上,提出了一种简单有效的无线局域网MAC层冲突解决机制(PBCR),主要通过均匀分布站点的退避计数器值来达到减少冲突的目的.建模的计算结果和仿真的统计结果都表明PBCR在性能上,包括吞吐量,公平因子以及发送延迟等方面比DCF有显著的提高. Based on DCF（distributed coordination function） scheme in IEEE802.11 standard. This paper proposed a simple and effective wireless LAN MAC （medium access control） mechanism called PBCR（partial backoff contention resolution）. Both analytical model and simulation result of PBCR was presented;which showed that PBCR improve the performance significantly, e. g. throughput ,fairness index, and average delay.
