摘　　要：为实现大气测量,构建一个无线传感器网络,给出了WSN节点的硬件结构配置.根据应用需求特点,采用S-MAC作为传感器网络的接入协议,重点对该协议的理论性能进行了分析,定量计算网络的延时、信道利用率和占空比等主要参数,最后采用仿真软件NS2对一跳网络和多跳网络分别进行仿真测试,仿真结果与理论分析结果一致.In order to realize the atmospheric measurement,has constructed a wireless sensor network,has given the WSN node hardware architecture disposition.And according to the application demand characteristic,Taken the S-MAC as the sensor network protocol,has carried on the analysis to this protocol theory performance with emphasis,has quantitative evaluated the network time delay,the channel use factor and the duty cycle and so on main parameter,as soon as finally used simulation software NS2 to simulate the one jump network and multi-jumps the network separately,the simulation result has been consistent with the theoretical analysis result.
