无线传感器网络是近几年发展起来的一种新兴技术,在条件恶劣和无人坚守的环境脓测和事件跟踪中显示了很大的应用价值。节点部署是无线传感器网络工作的基础,对网络的运行情况和寿命有很大的影响。部署问题涉及覆盖、连接和节约能量消耗3个方面。该文重点讨论了网络部署中的覆盖问题,综述了现有的研究成果,总结了今后的热点研究方向,为以后的研究奠定了基础。
Wireless Sensor Network (WSN), which is a novel class of computing and a new spot of information technology, is envisaged in application such as hostile environment surveillance and void event tracking. One fundamental issue in WSN is the deployment issue, which affects the performance and lifetime of the network. The deployment issue in WSN includes coverage, connectivity and energy-efficiency. The coverage problem in WSN is discussed in this paper. Therefore, the future work is presented.
