| 摘 要： | 媒质接入控制（Medium Access Control）是无线传感器网络设计的关键问题之一。由于无线通信模块是传感器节点能量消耗的主要来源，而媒质接入控制协议则直接控制着节点无线通信模块的活动，因此MAC协议节能效率的好坏将严重影响网络的性能。本文首先介绍了MAC层能量消耗的主要来源，阐述了无线传感器网络中MAC协议的研究内容和设计目标，并讨论了影响MAC协议性能的若干参数指标，随后介绍了几类典型的MAC协议，最后对MAC协议的发展方向进行了总结和展望。

| Abstract: | One of the key problem for Wireless Sensor Network (WSN) is the design of Medium Access Control(MAC) protocol. MAC protocol controls the activity of wireless communication module of sensor nodes, which is the major consumer of sensor energy. The energy efficiency of MAC protocol makes a strong impact on the network performance. This paper describes the sources of energy consumption in MC layer and the design of MAC protocol. Then some factors impacting on the performance of MAC protocol and metrics of performance evaluation are discussed. Finally, the future research direction is summarized. |
