| Abstract: | Locating on the application of wireless sensor networks, operation and management plays a vital role in. The sensor node localization, proposed one kind based on the received signal strength of probabilistic localization algorithm. Introduces the algorithm principle and implementation process, discussed the beacon node distribution on the performance of algorithm, finally compares the probabilistic localization algorithm and the least square algorithm in sensor node localization performance on the quality of. The simulation results show that, beacon node of unknown node positioning error has a greater effect; the positioning algorithm performance is better than the least squares algorithm. |
