基于无线传感器网络的资产智能化系统研究

资产智能化系统是智能大学系统的重要组成部分。文章通过对无线传感器网络的研究，提出“基于无线传感器网络的资产智能化系统”研究方案，并对方案中涉及到的系统功能架构、软硬件设计、路由协议设计等进行深入研究。由于该系统对网络的稳定性要求较高，而且网络中需要传输的参数较多，因此对于网络的路由协议，在最小跳数路由协议的基础上提出了改进，将节点剩余电池能量考虑其中，且以限制型广播方式广播路由信息，从而可以提高路由的有效性，大大降低数据传输的丢包率。

Assets Intelligence System Based on Wireless Sensor Network

Assets Intelligence System is a very important subsystem of Intelligent University System. Based on the studies of Wireless Sensor Network, this paper proposed the solution of ＂Assets Intelligence System on Wireless Sensor Network＂, and gave further study to all those factors involved： function framework of the system, design of the software and hardware, and routing protocol. As the stability is highly desired in the Assets Intelligence System and many parameter data are transmitted in the network, an improved method based on least-hop routing , in which node＇s remaining energy is considered, and the router information is restrictedly broadcasted. The proposed routing protocol can improve the efficiency of routing and greatly reduce the packet loss rate.
