Abstract
The RSSI positioning method has been a research hot topic in recent years. In this paper, the corrected parameter of RSSI distance measurement model is calculated by using the maximum likelihood method, and the coordinates of the nodes required are calculated by using the least square method, then the coordinates and parameters estimated by using the least square method preliminary are optimized and amended by using the gravitation search algorithm, which can not only improve the precision ofthe node coordinates, but also track the dynamic variation of the position model parameters. The application program of RSSI positioning system is embedded into the fire protection positioning system, and the position of the reference node coming from the serial port is received by the network node, The RSSI value of the position node inreceived by the reference node, and the final position of positioning node is calculated by using the presented algorithm. Finally, the parameter optimization results of the positioning model are verified according to the results of the fire protection positioning. The overall error of the RSSI positioning system is less, and the parameter can reflect that the change of the environment and the result is good as expected.关键词
