According to the analytical model that is used to studythe performance evaluation of the IEEE 802.11 DistributedCoordination Function (DCF), we analyze how the size of theinitial contention window works on the saturation throughputand the energy consumption. We also provide a new integratemetric to measure both the throughput and the energy consumption.Considering the situation of the constant stationnumber, we preset a optimal CWmin to achieve the maximumperformance. On the other hand, we propose a new algorithmcalled Self Adjusting CWmin(SACW) for the situation of thetime-varying station number. The paper gives the simulationresults by means of the new methods and compares them withthe original 802.11 protocol.
