SHIELD：使用mobiLe设备进行社会感知和紧急情况下的帮助
SHIELD: Social sensing and Help In Emergency using mobiLe Devices
摘要：
学校和大学校园面临着暴力犯罪的威胁，需要一个现实的计划来应对不可预测的紧急情况和灾难。现有的应急系统（例如，911，校园范围内的警报）是非常有用的，但提供延迟响应（往往几十分钟），不利用邻近或位置。有必要用基于邻近的系统来增强这类系统，以便对预防和威慑犯罪的尝试作出更直接的反应。在本文中，我们提出了盾牌，校园内的紧急救援和警报管理服务。它是一个完全分布式的无基础设施平台，基于邻近的信任和合作。它依赖于本地化的响应，使用蓝牙和/或WiFi在飞行中发送，以实现最小的响应时间和最大的可用性，从而增强了传统的紧急服务概念。对校园犯罪统计数据和WLAN痕迹的分析令人惊讶地显示，校园犯罪统计数据和校园移动用户时空密度分布之间存在很强的正相关性（超过55%）。这一结果为开发此类平台提供了动力，并指出了减少犯罪发生率的希望。我们还展示了一个原型应用程序的实现，在这种情况下使用。
英文摘要：
School and College campuses face a perceived threat of violent crimes and require a realistic plan against unpredictable emergencies and disasters. Existing emergency systems (e.g., 911, campus-wide alerts) are quite useful, but provide delayed response (often tens of minutes) and do not utilize proximity or locality. There is a need to augment such systems with proximity-based systems for more immediate response to attempt to prevent and deter crime. In this paper we propose SHIELD, an on-campus emergency rescue and alert management service. It is a fully distributed infrastructure-less platform based on proximity-enabled trust and cooperation. It relies on localized responses, sent using Bluetooth and/or WiFi on the fly to achieve minimal response time and maximal availability thereby augmenting the traditional notion of emergency services. Analysis of campus crime statistics and WLAN traces surprisingly show a strong positive correlation (over 55%) between on-campus crime statistics and spatio-temporal density distribution of on-campus mobile users. This result provides a motivation to develop such platform and points to the promise in reducing crime incidences. We also show an implementation of a prototype application to be used in such scenarios.
