摘要

本文提出了一种新的基于功率控制的基于竞争的无线传感器网络MAC协议，其中传感器节点可以按帧调整其传输功率水平。我们工作的主要贡献是使RTS, CTS, DATA和ACK帧的功率控制传输成为可能，同时保留MAC协议的碰撞和偷听避免属性，其中这些帧以最大功率传输。实验结果表明，与传统的传感器MAC协议相比，功率控制的传感器MAC协议能耗降低了30-99%。

PCSMAC: a power controlled sensor-MAC protocol for wireless sensor networks

In this paper a new power controlled contention-based MAC protocol is introduced for wireless sensor networks where sensor nodes can adjust their transmission power level on a per-frame basis. The main contribution of our work is to enable power controlled transmission of RTS, CTS, DATA and ACK frames while preserving the collision and overhearing avoidance properties of a MAC protocol where these frames are transmitted at the maximum power. Experimental results show that the power controlled sensor MAC protocol reduces the energy consumption by 30-99% comparing to the conventional sensor MAC protocol.
