To cope with the deficiency that the IEEE 802.11 DCF in wireless mesh networks deploys all the nodes in the same way and cannot dynamically adjust their contention windows according to their real time status
the authors divides contention window into initial contention window
successfully sent window and conflict contention window. This scheme designs three different back off algorithms for the different windows so that dynamically adjusts the ability of nodes to accessing channel in different status and improves the fairness and throughput of network.
