摘要 分析了IEE802.11无线局域网MAC层快速冲突分解算法,修改和扩展了ns-2网络仿真软件的IEE802.11无线局域网仿真模块,实现了ns-2对快速冲突分解算法的仿真。仿真结果表明,快速冲突分解算法提高了网络的平均吞吐量、减小了平均时延,但网络的时延抖动和公平性却更加恶化。 Analyzed the Fast Collision Resolution (FCR) algorithm of MAC layer in IEEE802.11 WLAN.Modified and extended the IEEE802.11 simulation module in ns-2.hnplemented the simulation of FCR algorithm in ns-2.Simulation results indicate,the FCR algorithm enhances the average throughput and cuts down the average delay,but degrades the jitter and fairness of IEEE802.11 WLAN.
