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(如火和气体)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公用事业仪表(电力、天然气和水)。第三类数据来自其他类型的传感器(例如，通过窗户散热)。我们将设计特定于应用的无线网络，从家庭环境中收集数据。这项工作将涉及网络拓扑控制、数据的路由和调度，以及在具有真实能量约束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。在开发家庭传感器网络策略时，必须考虑到不同类型的传感器有不同的应用需求(T1-T3)，一些传感器(例如车载传感器)是移动的，并且应用层的数据传输必须具有高可靠性。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、能量约束和特定于应用的设计是适用于实际传感器网络的拓扑控制、调度和路由以及传输协议的标准。开发这样的协议和传感器的智能电源是这个项目的主要目标。该项目的研究成果将提供以下好处：(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，用于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)将通知房主他们家的安全和能源效率。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.
