摘要： Two approximate computation methods were proposed to acquire the optimal transmitting probability and further to find the optimal contention window setting by analyzing the influence of the priority-based service differentiation of IEEE 802.11 Enhanced Distributed Channel Access (EDCA) on throughput. The optimal contention window setting can help yield the maximum aggregate throughput while maintaining the weighted proportional bandwidth differentiation among different traffic classes. Through validation by numeric evaluation and simulation, the results are proved to be very close to the theoretical value, and the optimal contention window setting can effectively optimize the throughput performance of the whole network.
