Dynamic Contention Window Adaptation (DCWA)

Dynamic Contention Window Adaptation (DCWA) - Dynamic contention window adaptation (DCWA) algorithm which adapts the contention window parameters for a single traffic class such that they are as small as possible to meet realtime conditions and large enough to cope with the current network load. The results reveal that the DCWA increases the overall cell capacity significantly compared to the fixed IEEE standard settings, it adaptively minimizes the contention delay when possible and maximizes the throughput when needed. Furthermore, we extended the method to handle competing high and low priority traffic and showed that the new mechanism can effectively protect voice from best effort traffic.
