一种MAC层延时均衡算法

摘要

The backbone network based on the structure of the clusters’networks in GAF protocolis utilized to research the problems caused by the tree⁃like hot spot of unfair delay and data packets loss. An MAC layer rotating sleep algorithm named ST⁃MAC which is based on the DMAC protocol is proposed and simulated by the software Matlab. The results show that the algorithm can balance the node data delays in different layers of the network tree and reduce both packet loss probability and energy consumption.%以GAF协议下簇头构成的骨干网络为基本架构，对树状热区造成的数据延时不公平、数据包丢失等问题进行了研究，提出了一种基于DMAC协议的MAC层轮值休眠算法ST⁃MAC。采用Matlab软件进行仿真实验，结果表明该算法均衡了网络树不同深度节点的数据延时，同时降低了丢包率和网络能耗。
