QoS provisioning for large-scale multi-ap WLANs

Jaehyuk Choi, Kang G. Shin
2012 Ad hoc networks  
There have been a plethora of research efforts to improve the WLAN performance, but most of them focused only on single WLAN environments without accounting for intercell contention.  ...  The EDCA focuses only on inter-flow priority distinction and has not considered the effect of inter-cell contention which significantly restricts its efficiency.  ...  Then, the other nodes estimate the sending rate based on received signal strength and the carrier sense threshold, and estimate the delivery rate based on SNR.  ...
