本文首先说明了本次课程设计的目的和软硬件环境，然后介绍了J-Sim的编译与配置；接下来，在第四章说明了无线传感器网络各结点的内部结构图，第五章和第六章是我们对J-Sim中无线网络包和传感器网络包所做的总体分析，在阅读第五章和第六章之前，需要先阅读第四章，理解各结点的内部结构图。最后，我们对一个简单的无线传感器网络进行了仿真-The paper first describes the purpose of curriculum design and hardware and software en

As we know, the energy needed for sensors should be electrical. So the rst step before start to work is to convert environmental energy to electrical one. Inside the node there are dierent components for sensing the area, collecting data and

这是一个关于无线传感器网络节点定位的加权质心定位算法的源程序-This is a weighted centroid localization algorithm of wireless sensor network node localization of the source program
