| Abstract: | RSSI and LQI as distance determination are discussed in the Zigbee wireless sensor network.Based on analysis and derivation of the Weighted Centroid Localization(WCL) algorithm,a node localization algorithm combining Weighted Centroid Localization with Zigbee technology is proposed,and simulations and practice are carried out.Because of low complexity and fast computing and low-resource allocation features of Zigbee technology,the WCL algorithm is of very important significance of application in wireless sensor network positioning. |
