摘要
在研究了802.11 DCF退避算法的基础上,通过引入优先级概念并采用时隙控制的方法,从提高不同用户的接入效率出发,提出了具有用户优先级的时隙MAC接入算法,使站点在窗口中选择退避时隙时尽量趋于均匀分布,从而达到分散冲突的目的。
Based on the research of back-off algorithm in 802.11 DCF, in order to improve the validity of accessing for different users, a time-slotted MAC protocol based on priority is proposed, and through the method of making the distribution of the chosen back-off window more evenly, we get our purpose of collision dispersed.
