- Abstract
Node localization is one of the most important supporting technologies in wireless sensor networks. In the practical application, the wireless sensor network nodes need to be positioned in real time, in order to monitor their location. This paper presents an accurate and real-time localization method based on historical data analysis (HDA-RTL). We analyze the behavior characteristics of the node’s historical position coordinates, and, according to the different analysis results, propose two positioning methods: real-time localization based on neighbor node location analysis and real-time positioning based on mobile anchor node. Then, we do the analysis through the simulation experiment. The simulation results show that the proposed method has significant advantages in positioning accuracy, success rate and power consumption.
