NeTS:Small:Supporting Multi-Missions in Wireless Sensor Networks

该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。无线传感器网络已被应用于许多军事和商业应用。然而，到目前为止设想的传感器网络是以单一任务为目标的，通常是为某些特定的应用而设计的。随着传感器的广泛部署，多个任务可能会共享共同的传感器来实现它们的目标，每个任务都有不同的要求。每个特派团对报告的数据类型、采样率、准确度和采样地点可能有自己的要求。从资源管理的角度来看，传感器网络支持多个任务而不是单个任务将是具有成本效益的。该项目的具体目标是支持无线传感器网络中的多任务。该项目解决了四个相互交织的问题：(I)将设计、实施和评估各种任务驱动的调度协议，以优化传感器的覆盖范围；(Ii)将开发新的技术，以快速有效地将任务切换代码/命令传播到受影响的传感器节点；(Iii)将设计任务驱动的传感器分配方案，以最大化网络效用；(Iv)将研究特定任务的网络配置，以满足动态和竞争任务的数据传输的实时要求。该项目将在理解和设计面向多任务的传感器网络方面取得重大的理论进步，并将开发全面的协议来支持传感器网络中的多任务。该项目的成功可能会对使无线传感器网络变得更负担得起、更适合商业、民用和军事应用产生更广泛的影响。该项目的成果将通过高质量的出版物和专题介绍广泛传播。拟议的研究还将与宾夕法尼亚州立大学的教育课程相结合。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Wireless sensor networks have been applied to many military and commercial applications. However, the sensor network envisioned so far is targeted for a single mission and often designed for some particular application. As sensors become widely deployed, multiple missions, each with different requirements, may share common sensors to achieve their goals. Each mission may have its own requirements for the type of data being reported, the sampling rate, accuracy, and location of the sampling. From resource management point of view, it will be cost effective for sensor networks to support multiple missions instead of a single mission. The specific goal of this project is to support multi-missions in wireless sensor networks. The project addresses four intertwined issues: (i) various mission-driven scheduling protocols which can optimize the sensor coverage will be designed, implemented, and evaluated; (ii) novel techniques will be developed to disseminate the mission switch code/command to the affected sensor nodes quickly and efficiently; (iii) mission-driven sensor assignment schemes will be designed to maximize the network utility; (iv) mission-specific network configurations will be investigated to meet the real-time requirements of data transfer for dynamic and competing missions. This project will make significant theoretical advances in understanding and designing multi-mission oriented sensor networks, and will develop comprehensive protocols to support multi-missions in sensor networks. The success of this project is likely to have a broader impact on making wireless sensor networks more affordable and amenable to commercial, civilian, and military applications. The results of the project will be disseminated widely through high quality publications and presentations. The proposed research will also be integrated with the education curricula at Penn State University.
