The sensor nodes of a wireless grain depot surveillance system are deployed in crystal grids, which provide lot of valid position information. To avoid the energy consumption unbalance of the single hop routing model adopted by LEACH prot

基于IP传感器的监控软件能够对分布在网络上的作为独立节点的传感器进行数据采集、校准等操作，而在监控软件开发中，首先就要解决网络通信问题。本文以搭载了Linux操作系统的IP传感器(ARM核)作为下位机，在其上编程实现Socket通信的服务器端，提供Socket客户端的并发访问。以装有Windows的计算机作为上位机，在其 上编程实现Socket通信的客户端，实现对Socket服务器端的访问，解决了IP传感器网络监控平台的通信问题。 -The monitoring software based o

一种新的基于链路质量指标或接收信号强度获取 节点相对位置的实用型高适应性定位算法，降低了无线传感网络节点定位对硬件的要求-A new index based on link quality or received signal strength for the relative position of nodes practical high adaptability positioning algorithm, reducing the wireless sensor network no

Awareness of the physical location for each node is required by many wireless sensor network applications. The discovery of the position can be realized utilizing range measurements including received signal strength, time of arrival, time di
