【Abstract】 Combining the Adaptive Step Glowworm Swarm Optimization(ASGSO) algorithm with BP neural network, a wireless channel modeling method based on ASGSO-BP is formed. The ASGSO-BP network with good data fitting performance is used to build a path loss model for wireless signal transmission in indoor environment to improve the accuracy of estimating the signal transmission distance. The model and RFID reader are used to detect the distance from the received signal strength value, and the distance is used in the LANDMARC algorithm for indoor three-dimensional spacelocating. The simulation results show that this method can significantly improve the accuracy and adaptability of wireless signal indoor locating. It is of great significance to promote the development of intelligent network connected vehicle technology.更多还原
