Multi-sender diversity and its application in the uplink of ieee 802.11 WLANs

Multi-sender diversity is an opportunity to exploit channel fluctuation in the situation where multiple senders compete for the same wireless resources. To utilize this diversity in the uplink of WLANs, we propose a novel distributed opportunistic scheduling scheme. Under the constraint of access fairness, the proposed scheme maximizes the system throughput. Analysis and simulation results show that the throughput gain increases with the number of stations.
