摘要翻译：
本文提出了一种利用无线信号检测“一起”行走的人群（群体移动性）和“单独”行走的人群（个体移动性）的新方法。我们利用多个无线嗅探器从使用移动设备的人身上广泛收集移动数据，并基于无线指纹识别相似性和群体移动性。我们提出了一种将嗅探器收集到的无线数据包初步转换为人的无线指纹的方法。然后，该方法通过寻找特定时间（动态/静态）的人群状态和动态人群的空间相关性来确定群体移动性。为了评估我们的方法的可行性，我们进行了真实世界的实验，从10个携带蓝牙低能量(BLE)信标的参与者那里收集数据，在办公室环境中进行了为期两周的实验。该方法的空间相关性平均为95%，群体移动性平均为79%。该方法成功地实现了：1）检测群体和个体的移动；2）根据群体的移动特性生成社会网络。

英文摘要：
This paper proposes a novel approach for detecting groups of people that walk "together" (group mobility) as well as the people who walk "alone" (individual movements) using wireless signals. We exploit multiple wireless sniffers to pervasively collect human mobility data from people with mobile devices and identify similarities and the group mobility based on the wireless fingerprints. We propose a method which initially converts the wireless packets collected by the sniffers into people's wireless fingerprints. The method then determines group mobility by finding the statuses of people at certain times (dynamic/static) and the space correlation of dynamic people. To evaluate the feasibility of our approach, we conduct real world experiments by collecting data from 10 participants carrying Bluetooth Low Energy (BLE) beacons in an office environment for a two-week period. The proposed approach captures space correlation with 95% and group mobility with 79% accuracies on average. With the proposed approach we successfully 1) detect the groups and individual movements and 2) generate social networks based on the group mobility characteristics.
