摘要：For traditional RSS location method has higher requirements of environmental factors, the workload in the design and calibration and operation phase is great and efficiency is lower, so it put forward a kind of wireless sensor network localization algorithm based on online calibration modeling of RSS anchor node. First of all, to filter the anchor nodes with weak signal and large uncertainty by using the standard deviation threshold method, and make on-line modeling on the relationship between the distance of anchor node and the unknown node and received signal strength. Secondly, using the cycle calibration way for real-time correction of the on-line model, then locate the unknown node by using the weighted average method, thus establish adaptive mechanism of the environmental factors to realize the real-time accurate positioning of the node. Finally, through simulation to indicate this method can effectively locate the unknown nodes in wireless sensor network and its precision meets the requirements, algorithm is simple and easy to implement with practical application value.
