Improvement of content window size selection algorithm for small 802.11n networks

Wi-Fi networks based on IEEE 802.11n standard have become very popular in private home networks. Some very basic elements of DCF (Distributed Coordination Function) media access schema have not been changed from the beginning of the standard. The authors analyze in this article, how much backoff time algorithm decreases the radio channel throughput. Then the new adaptive algorithm of improvement of contention window minimum and maximum values selection is proposed. This algorithm decreases the dead time in wireless network.
