摘要
在Adhoc网络中,节点间的不公平性会影响整个网络的性能。针对该问题,提出一种公平性算法——UTRVB。该算法用于有节点加入或移除的Adhoc网络,通过节点发送量与参考值比较大小来调节退避时间。仿真结果证明,该算法在不导致系统吞吐量严重下降的前提下,有效地改善了DCF机制的公平性。
In Ad hoc network, the unfairness between nodes affects the entire network performance. This paper presents a fairness algorithm UTRVB. The algorithm is applied to the nodes join or out of the Ad hoc network, and can adjust the backoff time by the amount of nodes and the size of the reference value. Simulation result shows that the algorithm can greatly improve DCF protocol fairness without affecting the system throughput in a serious decline.
