基于功率控制的无线传感器网络MAC协议研究

本文提出了一种无线传感器网络自适应功率控制MAC协议APC-SMAC。APC-SMAC协议首先通过建立基于最优邻居节点数的功率调度表，提高信道利用率，减少通信能耗，另一方面对干扰节点发送反馈帧控制其进入睡眠，从而提高了网络数据吞吐量，减少了网络延迟。实验结果表明该协议在网络吞吐量、网络时延和平均能耗上均有了较大的提高。

The Research of MAC protocol based on power control for wireless sensor networks

This paper presents an adaptive power control MAC protocol (APC-SMAC) for wireless sensor networks. At first, APC-SMAC protocol establishes the power schedule table based on the optimal neighbor nodes, to improve the channel utilization and reduce the communication energy consumption. On the other hand, sending a feedback frame makes the interfering nodes asleep, which will not only improve the network throughout but also minimize network latency. The experiment results show that the APC-SMAC protocol has a great improvement in network throughout, network latency and average power consumption.
