A throughput drop estimation model for two-link concurrent communications with non-bonded partially overlapping channels in IEEE 802.11n WLAN

摘要

The IEEE 802.11n wireless local-area net-work (WLAN) has been widely deployed due to ex-ible and high-speed data transmissions. However,the throughput of a link can be dropped by interfer-ences from other WLANs. Previously, we have stud-ied throughput drop estimation models for multiple-link concurrent communications with bonded 40MHzpartially overlapping channels (POCs), considering thechannel distance and the received signal strength (RSS)of the interfered link. In this paper, we present athroughput drop estimation model for two-link concur-rent communications with non-bonded 20MHz POCs.The effectiveness of the model is conrmed through ex-periments on different topologies where the estimatedthroughput well matches the measured throughput.
