抄録(英) As more and more access points (AP) are deployed to enable seamless coverage in a WLAN system, mobile nodes often have a chance to select a suitable AP. Meanwhile APs sharing the same channel are facing co-channel interference. Under the assumption that APs and nodes cooperate with each other, in this paper, we study how to perform joint AP selection and power control. APs measure channel cost and nodes measure link quality. Each node selects an AP that maximizes its potential throughput (calculated from channel cost and link quality). The relationship between estimated and measured channel costs is learned and used in estimating channel cost under new and unemployed power levels. Then, APs choose a power level that achieves the best tradeoff between self-cell channel cost and interference to adjacent cells. Nodes respond to the power changes and re-select an AP if necessary. The initial simulation results confirmed the effectiveness of the proposed schemes.
