SSI: Lebesgue Estimation for Minimizing Power Consumption in Ad Hoc Sensor Networks (Proposal No. 0427976)Abstract- This sensor proposal focuses on the development a new type of state-estimator (optimal observer) that minimizes the power requirements of wireless sensor networks employed in real-time feedback control systems. There is considerable ongoing work in optimizing sensor network protocols for minimizing power requirements. It is noted that most of the power consumed in a wireless sensor device is associated with executing a communication transmission event. This research seeks to determine a method whereby both the occurrence of communication events is minimized and the data content of each message is minimized while ensuring that the resulting state estimate does not exceed a specified error requirement. The intellectual merit of this research is in transforming a continuous-time and continuous-state model for the plant into a non-periodic discrete-time and non-uniform discrete-state system. The research will develop methods for analyzing and designing state estimators as stochastic timed automata within the framework of generalized semi-Markov processes. The broader impact of this research is setting the foundation for a wireless sensor network laboratory at the University of Arkansas. This laboratory is directed towards intelligent transportation systems in anticipation of the introduction of ad hoc sensor networks throughout highway infrastructure and motor vehicles. In outreach to K-12 students, the laboratory elevates the awareness of engineering careers to young people by showing explicitly how technology can be employed to increase safety, reduce congestion, and improve air quality. Additionally, the results will aid in the development of advanced collision avoidance and traffic regulation systems.

0427976号提案摘要-本传感器提案致力于开发一种新型的状态估计器(最优观测器)来最小化无线传感器网络在实时反馈控制系统中的功率需求。在优化传感器网络协议以最小化功率需求方面，有大量正在进行的工作。注意，无线传感器设备中消耗的大部分功率与执行通信传输事件相关联。该研究试图确定一种方法，在该方法中，通信事件的发生被最小化，并且每个消息的数据内容被最小化，同时确保所得到的状态估计不超过指定的误差要求。该研究的智能价值在于将对象的连续时间和连续状态模型转化为非周期离散时间和非均匀离散状态系统。这项研究将在广义半马尔可夫过程的框架内开发出分析和设计随机时间自动机的状态估计器的方法。这项研究的更广泛影响正在为阿肯色大学的无线传感器网络实验室奠定基础。该实验室的目标是智能交通系统，以期在整个高速公路基础设施和机动车辆中引入特别传感器网络。在对K-12学生的接触中，该实验室通过明确展示如何利用技术来提高安全性、减少拥堵和改善空气质量，提高了年轻人对工程职业的认识。此外，研究结果将有助于开发先进的防撞和交通监管系统。
