New MAC protocol based on power control for wireless sensor networks
一种基于功率控制的无线传感器网络MAC协议

This paper presented a basing on power control wireless sensor networks MAC protocol. This protocol used the node receive threshold value, then calculated the optimize transmission power. It could ultimately reduce node consume energy. In order to reduce the collision between node and the duration of the idle listening time, it added self-adaptive contention window size and fast back off scheme to make further save node energy. The result shows that the new MAC reduces the node energy consume and improves the throughput.
