A NON-COOPERATIVE SPATIAL MANAGEMENT GAME FOR HIGH EFFICIENCY WLAN (IEEE 802.11AX)

Abstract

IEEE 802.11ax has been identified to be a major player in next generation communication. However, the ubiquitous deployment of WLANs worsens the issue of channel interference which has dare consequences on throughput and latency. Previous techniques used to spatial coordination in dense networks have not properly addressed this issue. This paper extends non-cooperative games for spatial coordination in densely deployed WLANs via an AP administrator which is dynamically selected. Specifically, Kakutani’s fixed point theorem has been used as the metrics to prove that there is a fixed point which is the unique Nash equilibrium. Simulation results show the effectiveness of the strategy in reducing interference. The administrator allocates channels to the APs and enhances spatial reuse with minimum interference level of 6dB.
