Abstract

This paper presents a tracking system based on trajectory matching in WiFi network. When a user equipment appears in the monitored area, the system continuously intercepts WiFi beacon messages which are periodically issued by the user's equipments for finding accessable WiFi access point (AP). The system then infers the user's trajectory based on the MAC address and received signal strength indication (RSSI) indicated in the beacon message. We propose an estimation method to match the received electronic signal series along a user's trajectory to the most possible one of the predefined paths. The method mainly uses the variance of RSSI to determine the user pedistrian path. We develop a system prototype and conduct extensive experiments in real experimental environment. The experimental results show that the success rate is up to 68%, which proves that the method is applicable. Our tracking system can be widely applied in miscellaneous public spaces for a variety of applications, e.g., public park navigation.

基于Wi-Fi轨迹匹配的有效跟踪系统

本文提出了一种基于WiFi网络的轨迹匹配跟踪系统。当用户设备出现在监控区域时，系统不断拦截用户设备周期性发出的WiFi信标信息，寻找可接入的WiFi接入点(AP)。然后，系统根据MAC地址和信标消息中指示的接收信号强度指示(RSSI)推断用户的轨迹。我们提出了一种估计方法，将接收到的电子信号序列沿着用户的轨迹匹配到最可能的预定义路径之一。该方法主要利用RSSI的方差来确定用户的行走路径。我们开发了一个系统原型，并在真实的实验环境中进行了大量的实验。实验结果表明，该方法的成功率高达68%，证明了该方法的适用性。我们的跟踪系统可以广泛应用于各种各样的公共空间，如公园导航。
