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.
