This paper presents the design and performance evaluation of Concurrent-MAC, a MAC protocol for increasing concurrent transmissions and throughput in dense wireless LANs. Based on channel gain measurements and SINR values, sets of concurrent transmitters are identified by the backhaul of APs. A node gaining access to the channel, schedules one of its neighbors for concurrent transmission. Neighbor chosen for concurrent transmission can start transmitting on the channel, immediately after it overhears the privilege given to it for concurrent transmission. Our simulation results show that, in dense wireless LANs, Concurrent-MAC improves network throughput significantly compared to 802.11 DCF.
