摘要
AdHoc网络的应用环境以及其在商业上的潜在应用,使得它必须提供一定的服务质量(QoS)保证,但由于无线网络固有的特点,使得AdHoc网络中支持QoS面临许多新的挑战,发展合适的介质访问控制协议(MAC)是无线AdHoc网络得到广泛应用的一个关键,而其中退避算法又是MAC协议考虑的重点。对近年来国内外应用于AdHoc网络中的退避算法取得的研究成果作了概括和比较分析,提出了退避算法的评价指标和仿真实现方法,探讨了亟待解决的问题和未来研究的方向。
The application environments and potential applications in commerce require that wireless Ad Hoc networks should support Quality-of-Service （QoS）. In a wireless Ad Hoc network, supporting quality-of-service is very difficult because of the inherent characteristics of wireless channel. It is a key to develop suitable MAC protocol in wireless Ad Hoc network, and the backoff algorithm is the focal point considered in MAC protocol. The backoff algorithms of recent years on the media access control （ MAC ） protocol in wireless Ad Hoc networks is summarized and analyzed, and point out evaluation factor and simulation. The direction to the research in the future is point out.
