摘要
无线传感器网络以其自组织、低功耗、传输稳定等特点,被应用于监测平台、预警系统、高度危险无人区域的监控系统。由于无线传感器网络中传感器节点由电池供电,电池能量有限,因此能耗问题成为无线传感器网络发展和应用的阻碍,而节点调度是减少网络能耗、延长网络生存时间的重要机制之一。文章详细描述了几种节点调度算法,并对算法做出分析。
Wireless sensor networks have been applied to the detection platform, early warning systems and highly dangerous no man＇s land monitoring system because of their characteristics like self-organization, low power consumption, transmission stability. For the sensor nodes in the wireless sensor network are powered by batteries, and battery energy is limited, the problem of energy consumption hinders the development and application of wireless sensor networks, and the node scheduling is one of the important mechanisms to reduce network energy consumption and extend the lifetime of network. This article describes several node scheduling algorithms and analyzes the algorithms.
