In this paper we address the issue of improving the spatial reuse in virtual carrier sensing (VCS) mechanisms for wireless networks. The paper examines in detail the channel reservation mechanisms of IEEE 802.11 VCS and shows that its spatial reuse is sub-optimal in a number of scenarios. We also show that the area that should be reserved by the VCS depends on the distance between the transmitter and receiver. We then present a novel VCS scheme that optimizes spatial reuse by incorporating this… CONTINUE READING
