摘    要:传感器网络对于单个传感器而言具有高精度、高容错性、大覆盖区域等优点,在军事和商业领域都有巨大的应用前景。传感器节点一般由电池供电,且不易更换,所以传感器网络最关注的问题是如何高效利用有限的能量。文章对传感器网络的能源管理作了全面介绍,系统地分析了传感器节点各个部分的能源消耗情况和节能策略,以及通过剩余能源扫描掌握网络的能源信息。

关 键 词:传感器网络  能量管理  网络协议

Abstract:Potential advantages of having a sensor network as compared to a stand alone sensor are:greater precision,greater fault tolerance,and providing a very large area coverage.Generally,sensor nodes are provided electric energy by batteries,and replacing battery is very difficult because sensor nodes are distributed and the number of nodes is very large,so the most important issue about sensor networks is energy-efficiency.The paper entirely introduces energy man-agement of sensor networks,systematically analyzes energy consuming status and energy saving strategy for all parts of sensor node.Additionally,the paper introduces how to provide energy information through residual energy scanning.
Keywords:Sensor networks  Energy management  Network protocols
