Analysis and simulation results show that, compared with the ieee802. 11 binary exponential backoff ( beb ) algorithm and other algorithms that have been employed to address the fairness problem, the proposed qbwf algorithm is simpler and practical. also, by choosing appropriate parameters, the qbwf algorithm can effectively improve the channel access fairness and achieve a preferable trade - off between fairness and throughput
分析與模擬結果表明，與ieee802 . 11標準的二進制指數退避（ beb ）演算法和其它改善通道接入公平性的演算法相比，本文演算法更為簡單實用，且對于合適的參數取值，本文演算法能有效地改善通道接入的不公平性，並能在通道吞吐量的下降和通道接入公平性的改善之間達到一個較好的折衷。 -
Simulation is operated with ns2 under linux, and the simulation results show that, the presented algorithm is simpler and more practical, while it can improve the fairness index of ad hoc network to a large extent compared with the ieee802. 11 binary exponential backoff ( beb ) algorithm. it can make better use of the wireless channel by dynamically adjusting its backoff timer according to the network ' s contest situation. in addition, service differentiation can be achieved among flows with different qos requirements and thus the qos for medium access control in ad hoc network is improved
通過在linux系統下利用networksimulator （ ns2 ）模擬工具對演算法進行計算機模擬分析，結果表明，與ieee802 . 11標準採用的二進制指數退避（ beb ）演算法相比，該文所提演算法更簡單、高效，它能在很大程度上提高adhoc網路通道接入的公平性，並能動態地提供服務區分，保障對多媒體等多種實時業務的傳輸需求，同時，演算法可以根據網路當前具體的競爭激烈情況，動態調整退避時間值，從而提高通道的利用率。
