| 摘 要： | 无线传感器网络采用能量有限的电池供电,能量决定了传感器网络的生命期,传感器节点的能耗主要集中在介质访问控制层协议(MAC)上.如何降低传感器网络MAC层协议的能耗,成了解决能量问题的关键.文章从减少数据流量,增加射频模块休眠时间和冲突避免3个方面,深入剖析了当前经典的MAC协议,通过分析得出,在节省能耗上,应该综合考虑各种MAC协议的运用.

| Abstract: | Wireless sensor network(WSN) is mainly powered by limited batteries.Its life cycle is determined by the power.The energy consumption is embodied by the protocol of medium access control.How to reduce the energy consumption is the key to the application of the wireless sensor network.This paper analyzes the power consumption oriented MAC protocols of WSN through decreasing data stream,increasing sleeping time and collision avoidance respectively.Draw a conclusion that we should think over all the MAC protocol together. |
