Wireless Networks for Data collection form Sensored Homes

在这项提案中，我们寻求提供新的解决方案，以解决从部署在家庭中的各种传感器收集数据的问题。这些传感器报告三种数据：（T1）安全关键数据，（T2）具有经济价值的数据，以及（T3）用于规划和管理信息的数据。第一类数据来自监测物理现象（例如火灾和气体）和用于患者健康监测的身体安装传感器。第二种数据来自所有的公用事业仪表（电、气和水）。第三种数据来自其他类型的传感器（例如通过窗户的热损失）。我们将设计特定于应用的无线网络，以收集来自家庭环境的数据。这项工作将涉及网络拓扑控制，路由和调度的数据，和传输协议的广播和geocasting在大型传感器网络与移动的传感器与真实的能源约束。在制定家庭传感器网络的策略时，我们必须考虑到不同类型的传感器具有不同的应用需求（T1-T3），一些传感器（例如，身体安装的传感器）是移动的，并且应用级数据必须以高可靠性进行传输。这些要求不可能总是同时得到满足。因此，必须针对不同的性能指标进行权衡分析。效率、可扩展性、可靠性、能量约束和应用特定的设计是适用于真实的传感器网络的拓扑控制、调度和路由以及传输协议的标准。为传感器开发此类协议和智能电源是该项目的主要目标。该项目的研究结果将提供以下好处：（i）公用事业公司将有一种可扩展的，可靠的和廉价的方式来收集数据，以对其资源进行微观管理;（ii）医疗保健提供者将收到来自患者的实时数据;以及（iii）房主将被告知其房屋的安全性和能源效率。 该项目将产生先进的无线传感器网络领域的知识产权，用于监测复杂系统。

In this proposal, we seek to provide novel solutions to problems in gathering data from a variety of sensors deployed in homes. Those sensors report three kinds of data: (T1) safety-critical data, (T2) data with economic value, and (T3) data for planning and management information. The first kind of data comes from monitoring physical phenomena (e.g. fire and gas) and body-mounted sensors for health monitoring of patients. The second kind of data comes from all the utility meters (electricity, gas, and water). The third kind of data comes from other kinds of sensors (e.g. heat loss through windows). We will design application-specific wireless networks to gather data from home environment. The work will involve network topology control, routing and scheduling of data, and transport protocols for broadcasting and geocasting in large sensor networks with mobile sensors with real energy constraints. When developing strategies for home sensor networks, we must consider that different kinds of sensors have different application requirements (T1-T3), some sensors (e.g. body-mounted sensors) are mobile, and the application-level data must be transported with high reliability. These requirements cannot always be fulfilled at the same time. Therefore, trade-offs have to be analyzed with respect to different performance metrics. Efficiency, scalability, reliability, energy constraints, and application-specific designs are the criteria for topology control, scheduling and routing, and transport protocols that are applicable to real sensor networks. Developing such protocols and smart power supplies for sensors are the primary goals of this project. Research results from the project will provide the following benefits: (i) utility companies will have a scalable, reliable, and inexpensive way to gather data for micromanagement of their resources; (ii) health-care providers will receive real-time data from patients; and (iii) home owners will be notified about security and energy efficiency of their homes. The project will produce intellectual property in the field of advanced wireless sensor networks for monitoring of complex systems.
