Abstract: In IEEE802.11 infrastructure networks, stations sensing access point workflow can acquire enough information to judge whether there are hidden terminals. Using this feature, it proposes the detection algorithm of hidden terminals in the IEEE802.11 infrastructure network. The NS2 simulation results show that the proposed algorithm can significantly improve network performance in many scenes.

摘要: 在IEEE802.11基础型网络中,站点通过侦听接入点的工作过程,可以实时获得足够信息来判定是否存在隐藏站点。利用这一特性,提出了一种在IEEE802.11基础型网络中检测隐藏站点的算法,并通过NS2仿真对多种场景下该算法的性能进行验证。仿真结果表明,该算法可显著提高网络的性能。
