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

Abstract

The IEEE 802.11n wireless local-area net work (WLAN) has been widely deployed due to flex 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 40MHz partially overlapping channels (POCs), considering the channel distance and the received signal strength (RSS) of the interfered link. In this paper, we present a throughput drop estimation model for two-link concur rent communications with non-bonded 20MHz POCs.The effectiveness of the model is confirmed through ex periments on different topologies where the estimated throughput well matches the measured throughput
