Performance Study of IEEE 802.11 DCF with Optimal Contention Window

Abstract

The IEEE 802.11 protocol has achieved worldwide acceptance with WLANs with minimum management and maintenance costs. In order to maximize the throughput, stations had to spend many times to find out the best contention window. In our model, it is easy to derive the optimal contention window interval for a given network scale. We analyzed the behaviors of the model we proposed and found the optimal CW interval to maximize the throughput.
