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）采集的无线接触追踪数据，采集工作依托名为HYCCUPS Tracer的应用程序完成（访问地址：http://hyccups.hpc.pub.ro），该应用旨在从安卓（Android）智能手机中采集上下文数据。程序后台静默运行，可采集设备可用性与移动交互信息，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记录。接触数据采集通过AllJoyn框架实现，具体依托WiFi环境下的AllJoyn框架构建并销毁无线会话完成数据采集，追踪过程采用异步执行模式。本次追踪实验时长为63天，采集时段为2012年3月至5月，共有72名参与者，其中仅42名产生过至少一次接触记录。研究人员通过分析参与者的脸书（Facebook）个人档案，提取出了社交关系矩阵与用户兴趣标签。本追踪数据集及CRAWDAD数据集中的其他相关数据均可在MobEmu模拟器中进行解析，该模拟器已应用于布加勒斯特理工大学的所有研究论文，其公开访问地址为https://github.com/raduciobanu/mobemu，联系方式为[e-mail]
