The proposed protocol modifies the blind scaling of contention window (W) in binary exponential backoff (BEB) scheme of currently deployed WLANs. COSB is employed to adaptively scale-up and scale-down the W size during the backoff mechanism for collided and successfully transmitted data frames, respectively. It can achieve higher throughput and shorter delay compared to the conventional BEB mechanism in highly dense WLANs.}, title = {Channel observation-based scaled backoff mechanism for high-efficiency WLANs}, journal = {Electronics Letters}, issue = {10}, volume = {54}, year = {2018}, month = {May}, pages = {663-665(2)}, publisher ={Institution of Engineering and Technology}, copyright = {© The Institution of Engineering and Technology}, url = {https://digital-library.theiet.org/;jsessionid=1h594j6pkelb.x-iet-live-01content/journals/10.1049/el.2018.0617} }
