With the recent technological development in wireless networks, and multi-functional sensors with digital processing, power supply, diverse sensing and communication capabilities, wireless sensor networks have been undergoing a revolution that promises to have a significant impact throughout our society, from environmental applications (such as fire detection, flood detection, precision agriculture), health applications (such as telemonitoring of human physiological data) to home applications (such as smart environments and home automation). All of these applications are, in no doubt, quite beneficial to our Canadian society and economy.In this project, we focus on applications that require fine-grain monitoring of physical environments subject to critical conditions, such as fire, leaking of toxic gases and explosions. These scenarios pose a great challenge to sensor network protocols which must provide a fast, reliable, fault-tolerant and energy-aware channel for events diffusion, which meet the requirements of query-based, event-driven and periodic sensor networks application scenarios. These requirements have to be met even in the presence of emergency conditions that can lead to node failures and path disruption to the central controller.It is, therefore, our goal to design of novel fault-tolerant, reliable, low latency and energy aware framework for wireless sensor networks, and a web-based security surveillance for critical conditions monitoring of context aware physical environments. In such situations, it is important that information be sensed from the physical environments while the emergency state is in progress, since more precise information can be used by security and rescue teams, for operation management and improved strategic decisions.The Pis are responding to the growing demands from the public safety and emergency preparedness department within Ontario and Canada to design a robust and reliable wireless sensors infrastructure for critical monitoring of context aware physical environments and protecting our critical infrastructures.

随着近年来无线网络技术的发展，以及具有数字处理、供电、多样化传感和通信能力的多功能传感器，无线传感器网络正在经历一场革命，从环境应用到整个社会都将产生重大影响（如火灾探测、洪水探测、精准农业），从健康应用（例如远程监测人体生理数据）到家庭应用（例如智能环境和家庭自动化）。毫无疑问，所有这些应用都对我们加拿大的社会和经济非常有益。在这个项目中，我们专注于需要对处于关键条件下的物理环境进行精细监测的应用，例如火灾，有毒气体泄漏和爆炸。这些场景对传感器网络协议提出了很大的挑战，传感器网络协议必须提供一个快速、可靠、容错和能量感知的事件扩散通道，以满足基于查询、事件驱动和周期性的传感器网络应用场景的需求。这些要求必须得到满足，即使在存在的紧急情况下，可能会导致节点故障和路径中断到中央控制器。因此，我们的目标是设计一种新的容错，可靠，低延迟和能量感知框架的无线传感器网络，和基于Web的安全监控的关键条件监测上下文感知的物理环境。在这种情况下，重要的是在紧急状态正在进行的同时从物理环境感测信息，因为安全和救援团队可以使用更精确的信息，运营管理和改善战略决策。PI正在响应安大略和加拿大公共安全和应急准备部门日益增长的需求，设计一个强大而可靠的无线传感器基础设施用于对环境感知物理环境进行关键监控，并保护我们的关键基础设施。
