Improvement for contention window mechanism using the transmission state and random backoff history in IEEE 802.11 WLANs

In IEEE 802.11 WLAN networks, the Binary Exponential Backoff (BEB) protocol has been used to avoid collisions due to channel errors, but it is less efficient for dense networks with many transmitting nodes. In this work, we propose a new scheme for adapting the contention window...
