| 摘 要： | 移动代理传感器网络(SENMA)由移动代理节点负责数据处理、接入、转发、传输和路由等工作,更加节能。通过分析指出SENMA网络进行节点定位最适于采用基于距离定位算法,依据网络特点基于接收信号强度指示(RSSI)测距技术较为可行。依据信道RSSI特点,提出了一种加权质心定位算法,并利用Matlab编程进行了仿真验证,证明了其性能优于极大似然估计定位算法,更为适用于SENMA网络。

| Abstract: | In this paper,Sensor Network with Mobile Agents (SENMA) is introduced.In SENMA,the mobile agent node is responsible for data processing,access,transmission,routing,etc.Through analysis,the node localization in SENMA network is most suitable for using range-based localization algorithm,and it is better to measure distances by Received Signal Strength Indication (RSSI) than other.A weighted centroid localization algorithm is given based on RSSI for SENMA,the simulation result indicates that the performance of... |
