Sliding contention window (SCW) towards backoff range-based service differentiation over IEEE 802.11 wireless LAN networks.

Sliding contention window (SCW) towards backoff range-based service differentiation over IEEE 802.11 wireless LAN networks.

A number of works have tried to adjust the contention window in order to provide differentiated quality of service in IEEE 802.11-based wireless networks. By giving different service classes different CWs, the distribution of backoff intervals (chosen randomly, on the interval [O, CW]) will reflect...
