A new backoff scheme based on channel state for IEEE 802.11e WLANs

摘要：

The paper has brought forward a new access mechanism，which is called Dynamic Enhanced Distributed Channel Access(DEDCF)，this mechanism connects a parameter of channel state(CS)with backoff windows.back-off window is dynamically adjusted change by CS.Furthermore，Backoff Time(BT)is divided into two decreasing phases：reduction of one by one and reducdon of exponent.Simulative experiments have certified that mechanism improves the performance of video and data with uninfluenced performance of voice.
