On Clock Synchronization of Wireless Sensor Networks

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.
