基于信标节点RSSI自校正的WSN三维定位
3D localization in WSN based on beacon node RSSI self-correcting
摘要
Abstract
Based on the previous research on quadrlateration and RSSI (received signal strength indicator) ranging mode, a new 3-dimentional (3D) location algorithm based on the RSSI self-correcting of beacon node was proposed to solve the problems, such as the low location accuracy and the excessively dependent on the infrastructure, which existed on the current 3D location algorithms in wireless sensor networks (WSN). In this algorithm, the beacon node played the role of blind node to correct the RSSI measurement errors and the network location errors, and then weighted average method was a-dopted in the calculation. Simulation results show that the algorithm can improve both the 3D location accuracy and stability, thus it has a broader application.关键词
