摘要：
According to our studies, the current contention resolution algorithm adapted in wireless ad-hoc networks, binary exponential backoff scheme, does not function well in multi-hop environments due to its several performance issues and technical limitations. For example, unfair channel access, intensive collision, and throughput degradation are several widely known issues. Besides, BEB cannot support multimedia traffic since it does not include any priority mechanism. In this paper, we put forth a simple, fair channel access, priority provision, and well performed contention resolution algorithm for multi-hop wireless ad-hoc networks. Simulations are conducted to evaluate the performance scheme. As it turns out, the results show that the proposed algorithm can effectively alleviate the fairness problem and support multimedia traffic in multi-hop wireless ad-hoc networks.
