Abstract
The algorithm based on the beacon node localization is a research hotspot in the field of wireless sensor network. For circular distribution beacon group, we found that the optimal number of beacon is 5, and one is located in the centre of the circle, the remaining four evenly distributed on the circumference of a circle; For rectangular ROI, take advantage of the beacon group can pinpoint areas for the square, the whole network is divided into a grid, use a traveling salesman algorithm to get the beacon for optimal moving path; Based on five beacon node localization model in this paper, we put forward a novel region segmentation centroid localization algorithm (RDCLA), by comparing three groups of RSSI values, the node is locked into a triangle area, using centroid algorithm to locate the node; The algorithm principle is simple and has low computing complexity and has nothing to do with the network topology; The simulation results show that compared with TCLA and WCLA positioning accuracy has large improvement, and are suitable for all kinds of the size of the wireless sensor network.
