Indoor Location and Data Security of Traffic Flow based on Fingerprint Database Filtering

With the development of urbanization, the number of vehicles is gradually increasing, and the vehicle is gradually developing toward the direction of intelligence. Internet of vehicles technology is gradually entering millions of homes. In this paper, traffic flow data location and security algorithm are designed, and node data verification is carried out. This paper mainly studies the influence of fingerprint database filtering and matching methods on WiFi indoor locations based on RSSI. The results of this paper show that the designed system can transmit traffic flow data safely and accurately.
