基于无线传感器网络的温湿度监测系统设计与实现

Design and Implementation of Temperature and Humidity Monitoring System Based on Wireless Sensor Networks

给出了以CC2430芯片为核心的环境监测无线传感器网络实现方案。设计中充分考虑到节点的剩余能量、链路质量和节点负载等因素,提出了一种能耗均衡树算法,使网络节点的负载逐渐趋于均衡,解决了因负载分配不均衡,使得网络节点出现过早失效、缩短网络寿命问题。实验表明,算法可均衡节点负载,延长网络的生存时间,实现网络的长效运行。

A wireless sensor networks environmental monitoring based on CC2430 is designed.Considering the node's residual energy,RSSI and load,an algorithm for the balance of energy consumption is proposed to reduce the unbalance of load causing premature death of sensor nodes and shortens the network lifetime.The simulation results prove the good performance in balancing the node's load,extending the lifetime and prolonging the lifetime of the whole network.
