Abstract

The existence of hidden and exposed nodes can have a significant negative impact on the performance of IEEE802.11 networks. Such nodes can increase the probability of collisions and limit the spatial reuse on the channel. The value of the Physical Carrier Sensing Threshold (PCST) is instrumental in the presence of such nodes in a system. This paper presents a new adaptive physical carrier sensing management algorithm for wireless networks. Our KAPCS2 management system maximizes the aggregate system throughput by identifying and addressing problem nodes. It incorporates 802.11k Radio Resource Measurements (RRM) on each node to enable on-line tuning of the PCST.
