Wireless Networks for Data collection form Sensored Homes

在本提案中，我们寻求为从部署在家庭中的各种传感器收集数据的问题提供新颖的解决方案。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，（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（例如火和气）和用于监测患者健康的身体安装传感器。第二类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（例如通过窗户的热量损失）。我们将设计特定应用的无线网络，从家庭环境中收集数据。该工作将涉及网络拓扑控制、数据路由和调度，以及在具有实际能量限制的移动传感器的大型传感器网络中用于广播和地理广播的传输协议。在制定家庭传感器网络的策略时，必须考虑不同类型的传感器具有不同的应用需求（T1-T3），一些传感器（如身体安装的传感器）具有移动性，并且应用级数据必须具有高可靠性传输。这些要求不可能总是同时得到满足。因此，必须根据不同的性能指标来分析权衡。效率、可扩展性、可靠性、能源约束和特定应用设计是拓扑控制、调度和路由以及适用于真实传感器网络的传输协议的标准。为传感器开发这样的协议和智能电源是这个项目的主要目标。该项目的研究成果将带来以下好处：(i)公用事业公司将有一种可扩展、可靠和廉价的方式来收集数据，以便对其资源进行微观管理；㈡保健提供者将收到患者提供的实时数据；（三）业主将被告知其房屋的安全和能源效率。该项目将产生用于监测复杂系统的先进无线传感器网络领域的知识产权。

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.
