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。
