Densification of access points (APs) in wireless local area networks (WLANs)\nincreases the interference and the contention domains of each AP due to\nmultiple overlapped basic service sets (BSSs). Consequently, high interference\nfrom multiple co-channel BSS at the target AP impairs system performance. To\nimprove system performance in the presence of multi-BSSs interference, we\npropose a decentralized AP selection scheme that takes interference at the\ncandidate APs into account and selects AP that offers best\nsignal-interference-plus noise ratio (SINR). In the proposed algorithm, the AP\nselection process is distributed at the user stations (STAs) and is based on\nthe estimated SINR in the downlink. Estimating SINR in the downlink helps\ncapture the effect of interference from neighboring BSSs or APs. Based on a\nsimulated large-scale 802.11 network, the proposed scheme outperforms the\nstrongest signal first (SSF) AP selection scheme used in current 802.11\nstandards as well as the mean probe delay (MPD) AP selection algorithm in [3];\nit achieves 99% and 43% gains in aggregate throughput over SSF and MPD,\nrespectively. While increasing STA densification, the proposed scheme is shown\nto increase aggregate network performance.\n
