Evaluation of an efficient collision resolving protocol for highly populated wireless networks
Gill R. Tsouri, Ruslan Dautov · 2011
An efficient random medium access control protocol for highly populated wireless networks is proposed and evaluated using computer simulations. The algorithm is based on non-coordinated resolving of collisions during a contention period at the beginning of frame transmission. By the end of the contention period a single node has access to the link with very high probability. This approach presents an alternative to the widely used exponential backoff approach which renders the link idle for a substantial proportion of time. We investigate the impact of varying packets length and non-optimal use of parameters on performance. The results demonstrate the robustness of the protocol and a much higher saturation throughput for highly populated wireless networks when compared with existing state-of-the-art. For tested scenarios, the saturation throughput varies slightly around 0.8 for hundreds if nodes sharing the same collision domain.
