无线网络中一种公平性的退避算法

A wireless network fairness algorithm for the backoff

为了提高信道吞吐量和访问信道的公平性,文章提出一种公平性退避算法。该算法一个新的特征就是通过监听机制达到信道的公平访问,每个节点监听到成功地传输后复制发送方的退避值为自己下一次传输的退避值。模拟结果显示,公平性退避算法的执行效果优于二进制指数退避算法(BEB)和倍数增加线性减少退避算法(MILD)。

To improve the channel throughput and fairness of random access channels, a fairness backoff algorithm（FBA） is proposed. A novel feature of the FBA scheme is the sensing mechanism to keep fairness. Every active node sensing the successful transmission copys the transmitter＇s backoff interval as the next backoff intervals themselves. Simulation results indicate that the FBA scheme out-per-forms BEB and MILD.
