This paper focuses on the analysis of carrier sensing mechanisms adopted by the 802.11 medium access control. Through an analytical study, a mechanism to dynamically set the Carrier Sensing Range is presented. The mechanism improves the spatial reuse by avoiding the interference of neighbor nodes. Simulation results show that setting the Carrier Sensing Range according to the proposed model optimizes the network goodput. Additional simulations without Virtual Carrier Sensing enabled confirm the… CONTINUE READING
