Abstract: In order to solve the problem of poor ranging accuracy and robustness of received signal strength indication (RSSI), a signal strength localization algorithm based on rank filter and Fibonacci tree optimization (RF-RSSI-FTO) was proposed. First, the rank filtering method was used to remove the interference of the RSSI value to improve the accuracy and robustness of the ranging. Then, the Fibonacci tree optimization algorithm was introduced to optimize the global and local search of the positioning coordinates to reduce the positioning error. Simulation results show that the RF-RSSI-FTO algorithm can effectively improve ranging accuracy and robustness, enhance the global and local search ability, and improve positioning accuracy.
