Abstract:The principle of nodes' localization in wireless sensor networks is analyzed. The nodes' distance measure and localization process are described. CC2420 RF module and LPC2138 MCU are used to be the hardware platform of nodes on the location experiment. The results of two RSSI-based localization algorithms (Trilateration and Maximum Likelihood Estimation) in Wireless Sensor Networks are presented. Simulation model is built by matlab. Location error influenced by distance measure error and network connectivity is analyzed.
