| 摘 要： | 简要分析了无线传感器网络(W SNs)MAC层协议,针对MAC协议在节能和时延方面的不足,提出了一种基于生成树的MAC协议(ST-MAC)。以汇聚点为根节点,创建一个由网络中所有节点组成的生成树。ST-MAC采用TDMA接入方式,其固有的低工作周期提高了网络性能。性能分析和实验结果表明:相对S-MAC,ST-MAC在能量节省和时延方面有较好的效果。

| Abstract: | Simple analysis is made in MAC for wireless sensor networks.Taking account of the drawbacks in energy efficient and latency of the existing MAC protocols,a MAC protocol based on a spanning tree(ST-MAC)is proposed.With sink node as root node,a spanning tree of all the nodes in the networks is created.ST-MAC adopts TDMA,whose inherent low duty cycle improves the performance of the networks.The performance analyses and experimental results show that ST-MAC is better than S-MAC in terms of both energy efficient and latency. |
