摘　　要：无线传感器网络由于能量受限,传感器节点的生存周期取决于节点的能量消耗。本文分析了典型的S-MAC协议和T-MAC协议,研究了这些协议的工作原理。针对节能问题,建立了能量消耗的数学模型。对无线传感器网络的MAC协议,进行了MATLAB软件仿真,做出了关于能耗问题的曲线图,仿真结果表明在同等条件下T-MAC协议耗能较少,且能较好的满足通信的时延性。The wireless sensor networks nodes＇energy is limit. Sensor nodes＇life cycle is depended on the power energy - consumption. In this paper the S - MAC and T - MAC protocol is analyzed, and their principle is researched. For the energy - efficiency a mathematic mode is proposed and uses the MATLIB software to emulate them, energy - consumption chats is given. The result shows that the T - MAC protocol is better for energy -efficiency in the case of the same condition.

关 键 词：传感器网络 MAC协议 S-MAC协议 T-MAC协议 能量有效性
