【摘要】 详细分析了无线传感器网络(W SN)中时钟同步技术的特点、种类及其在W SN设计中的作用.给出了一种全面的研究体系内容.提出了两种技术方案:一种是以在传统局域网范围内实现的精度达100ns的同步技术为基础进行无线电媒介下的改造;另一种是Internet的NTP协议的精简及向W SN的移植.*更多还原

【Abstract】 This paper gives a detailed analysis on the characteristics and category of clock synchronization and its application to the design of wireless sensor networks(WSNs).A comprehensive research architecture is presented,and two technical schemes are proposed,i.e.,the reform of LAN-based 100ns precision clock synchronization technique under radio media, and the simplification of network time protocol(NTP) and its transplantation into WSNs.更多还原
