摘要: As the latest amendment of IEEE 802.11 standard, 802.11n allows a maximum raw data rate as high 600 Mbps, making it desirable candidate for wireless local area network (WLAN) deployment. In typical deployment, coverage areas nearby access points (APs) usually overlap with each other to provide satisfactory and seamless mobility support. Clients tend associate (connect) AP strongest signal strength, which may lead poor client throughput overloaded APs. Although number association schemes have been proposed WLANs in literature, challenges brought by new features not thoroughly studied nor impact legacy 802.11a/b/g clients WLANS on association. To fill this gap, paper, we explore heterogeneous (802.11a/b/g/n). We first present bi-dimensional Markov model estimate uplink downlink formulate into an optimization problem, aiming at providing bandwidth proportional its usable rate. Based model, propose on-line algorithm under condition that can acquire timely information all associated Furthermore, densely deployed APs, another lower complexity, takes full advantage transmissions simply associating different types conducted extensive simulations experiments validate algorithms. The results show our algorithms significantly improve both aggregated various scenarios, compared previous schemes. Our also confirm effectiveness enhancing throughput, maintaining fairness among clients, balancing load
