摘要： A method and system for increasing the overall network throughput over a wireless local area network (WLAN). Specifically, in one embodiment of the present invention, the dynamic selection of an initial value for a contention window in the Distributed Coordinated Function (DCF) mode is determined according to the load conditions over the WLAN in a method and system. Stations and access points within a WLAN monitor conditions within the network to establish an initial value for the contention window, also called a minimum contention window value, which is lower than that set by the IEEE 802.11 communication standard. Some factors to consider in determining the load conditions include but are not limited to the following: number of transmissions; number of receptions; and number of collisions.

摘要： A method and system for increasing the overall network throughput over a wireless local area network (WLAN). Specifically, in one embodiment of the present invention, the dynamic switching between the Distributed Coordination Function (DCF) and Point Coordination Function IEEE 802.11 access modes is determined according to the load conditions over the WLAN in a method and system. Stations and access points within a WLAN monitor conditions within the network to determine which access mechanism is most optimum for the current load conditions. Some factors to consider in determining the load conditions include but are not limited to the number of transmissions, number of receptions, and number of collisions.
