Abstract
A method to adaptively control CW sizes in order to enhance throughput of real-time traffic even when an AP accept large number of real-time traffic is disclosed. Since default CW sizes for real-time flows are set to small values in order to achieve the service differentiation, real-time flows cannot meet their requirements when collisions between real-time flows often occur. When increasing the size of CW in an AC, the one in other ACs are also increased if the service differentiation among ACs has to be maintained. And in case of decreasing the size of CW in an AC, the one in other ACs are also decreased if the service differentiation has to be maintained.
