Wireless contacts trace collected at the University Politehnica of Bucharest in the spring of 2012, using an application entitled HYCCUPS Tracer (http://hyccups.hpc.pub.ro), with the purpose of collecting contextual data from Android smartphones. It was run in the background and collected availability and mobile interaction information such as usage statistics, user activity, battery statistics, or sensor data, but it also gathered information about a device's encounters with other nodes or with wireless access points. Encounter collection was performed using AllJoyn. The data was collected by constructing and deleting wireless sessions using the AllJoyn framework based on WiFi. Tracing was executed asynchronously. The duration of the tracing experiment was 63 days, between March and May 2012, and had 72 participants, out of which only 42 had at least one contact. By analyzing the participants' Facebook profiles, the social connections matrix was extracted, as well as the users' interests. The trace (and others from the CRAWDAD collection) is parsed within the MobEmu simulator (used in all UPB's papers), publicly available at https://github.com/raduciobanu/mobemu. ; [e-mail]

本数据集为2012年春季于布加勒斯特理工大学（University Politehnica of Bucharest，简称UPB）采集的无线接触追踪数据集，所用工具为名为HYCCUPS Tracer的应用程序（访问地址：http://hyccups.hpc.pub.ro），其设计目标为从安卓（Android）智能手机中采集上下文数据。该应用在后台运行，可采集设备可用性与移动交互相关信息，包括使用统计、用户活动、电池状态统计及传感器数据，同时还会收集设备与其他节点或无线接入点的接触信息。接触信息采集采用AllJoyn框架完成，数据采集过程通过基于WiFi的AllJoyn框架构建并销毁无线会话实现，整个追踪流程以异步方式执行。本次追踪实验周期为63天，时间跨度为2012年3月至5月，共有72名参与者，其中仅42名至少产生过一次接触记录。研究人员通过分析参与者的Facebook个人主页，提取出了社交关系矩阵与用户兴趣标签。本数据集（及CRAWDAD收录的其他数据集）可在MobEmu模拟器中进行解析（该模拟器已被UPB的所有相关论文所采用），其公开仓库地址为https://github.com/raduciobanu/mobemu。联系方式：[e-mail]
