ABSTRACT
The wireless mesh network (WMN) is one of the most promising wireless technologies to achieve high network capacity at a reasonable cost. In WMNs using contention-based medium access method, there may be a lot of collisions and retransmissions in the nearby mesh point collocated with a mesh portal (MPP) due to the concentration of traffic. To reduce the contention around the MPP, an efficient medium access control (MAC) should be designed. In this paper, we propose an adaptive hybrid MAC (AHMAC) scheme which selectively uses point coordination function (PCF) and distributed coordination function (DCF) to effectively carry traffic concentrated on an MPP. For performance evaluation, we considered a mesh network consisting of IEEE 802.11s devices with single- or multi-interface environments. Simulation results showed that an AHMAC can accommodate around 60% more users in single- and multi-interface environments compared with conventional DCF.
