Abstract

The apparently never ending widespread of wireless networks requires an enhanced multimedia application support. In this paper, we show how to improve the performance of EDCA in terms of throughput, frame delay and station scalability, through the effective cooperation of two backoff mechanisms: EDM and CWD. Simulation results confirm our previous analytical study and enable the discussion about how to improve relevant Quality of Service metrics, considering different channel bit rate and network load.
