A number of other important tasks can not be effectively carried out without proper time synchronization in wireless sensor networks. So time synchronization is an important part of wireless sensor network, and it has high research value. In this paper, an improved IROS synchronization algorithm is proposed based on the study of ROS synchronization protocol. By studying the correlation between the...
The current time synchronization algorithms for wireless sensor networks have some defects, which include sensitive error data, huge energy consumption and long synchronization convergence time. The Flooding Broadcast Time Synchronization algorithm based on voronoi diagram (FBTS) is presented to work out related issues. The basic synchronization idea of the algorithm is to record a broadcast message...
With the development of precision agriculture, environmental monitoring is significant. This paper describes how to design and implement a Multi-layer Soil temperature monitoring system based on WCDMA network and WEB technical integration. This System includes WCDMA developing module, multi-layer temperature sensors and a B/S model monitoring system depolied on server. Via 3G network to setup a link...
