Study and test on wireless sensor network monitoring system of the wetland water environment based on cluster-head selection

为解决湿地水环境污染监测问题,本文设计了无线传感器网络湿地水环境监测系统,在中国吉林省向海湿地进行试验。针对无线传感器网络监测的水环境的p H值和N量与常规方法监测的参数进行对比,相对误差平均值分别为2.2%和2.88%,测量精度可以满足湿地水环境的应用要求。在网络层路由算法采用了能量自适应的簇首选择机制的算法,经仿真验证概算法使网络生存时间延长了近25.75%。

The system was designed in order to solve the problem of wetland water environment pollution monitoring,and the experiment was taken in Xiang Hai Wetland in Jilin province of China.The monitoring parameters p H and N with those by conventional method were compared,the average value of relative error were 2.2% and 2.88%,the measurement accuracy can meet the application requirements of the wetland water environment.In network layer,the adap-tive algorithm of cluster-head selection mechanism was used,and the simulation results show it extends the network lifetime nearly by 25.75%.
