Eccs-0801549MitterObjective:The proposed research is to develop a universal framework for the analysis and design of Network Embedded Feedback Systems (NEFS). Any such theoretical development requires a theory of distributed control where sensors and actuators are linked to distributed controllers through communication links, such as a wireless network. Two key ingredients of such a theory are a unified view of communication control and a systematic view of distributed algorithms for problems of optimization and control under uncertainty. Over the last few decades, there are extraordinary advances in microelectronics, in software (as reflected by modern object-oriented systems, design patterns and middleware) and in communication networks (including protocols, wired and wire-less networking). Today, everything is getting sensed: vehicles, roads, buildings, airspaces, and the environment. Sensors are getting smaller, cheaper, more pervasive and powerful. The benefits of pervasive networked sensing are compelling. Applications include monitoring wildlife habitats for conservation programs, waterways to understand long-term environmental effects, urban areas for intruder detection, and various components of automobiles for integrated safety and warning systems.Intellectual Merit:The rapid convergence of sensing, computing and communication technologies on cost effective, low power, miniature devices will enable a revolution in NEFS. These are distributed control/estimation systems with large numbers of sensors, actuators, and computing nodes that communicate over wire-line or ad hoc wireless networks. Enabling NEFS across this extremely diverse application set requires a unified analysis and design methodology. The feedback nature of NEFS demands extra-ordinary reliability. For this, they need to adaptively respond to unpredictable events such as node failures, communication link failures, and network conditions such as latencies and packet losses. These are the core problems that are addressed in the proposal.Broader Impacts:The scientific impact of the proposed research will stem from efforts at developing fundamental system-theoretic analysis and modeling methods for NEFS. This fundamental theoretical development is vital to enable subsequent design and analysis research for NEFS. The technological impact of the proposed research is that it will provide insight into the systematic, cost-effective design of NEFS in a variety of applications. This research is linked to a layered architecture approach which permits design tradeoffs such as computational resource allocation, communication protocol choice, and power/reliability compromises to be readily navigated. The aim is to link this research to a doctoral program by developing a graduate course on DistributedControl over Networks.

ECCS-0801549 Mitter目的：提出的研究是开发一个通用的框架，分析和设计的网络嵌入式反馈系统（NEFS）。任何这样的理论发展都需要分布式控制理论，其中传感器和执行器通过通信链路（如无线网络）连接到分布式控制器。这样一个理论的两个关键成分是一个统一的观点，通信控制和分布式算法的不确定性下的优化和控制问题的系统观点。在过去的几十年里，微电子学、软件（如现代面向对象系统、设计模式和中间件所反映的）和通信网络（包括协议、有线和无线网络）都取得了非凡的进步。今天，一切都被感知：车辆，道路，建筑物，空域和环境。传感器变得越来越小，更便宜，更普遍和强大。无处不在的网络传感的好处是引人注目的。应用包括监测野生动物栖息地的保护计划，水道，了解长期的环境影响，城市地区的入侵者检测，和各种组成部分的综合安全和报警system.Intellectual优点：快速收敛的传感，计算和通信技术的成本效益，低功耗，微型设备将使一场革命的NEFS。这些都是分布式控制/估计系统，具有大量的传感器，执行器和计算节点，通过有线或自组织无线网络进行通信。在这个极其多样化的应用程序集上启用NEFS需要统一的分析和设计方法。NEFS的反馈性质需要非凡的可靠性。为此，它们需要自适应地响应不可预测的事件，例如节点故障、通信链路故障以及网络条件，例如延迟和数据包丢失。更广泛的影响：拟议的研究的科学影响将源于为NEFS开发基本系统理论分析和建模方法的努力。这一基本理论的发展是至关重要的，使后续的设计和分析研究NEFS。拟议的研究的技术影响是，它将提供深入了解系统的，具有成本效益的设计NEFS在各种应用。这项研究是链接到一个分层的架构方法，允许设计权衡，如计算资源分配，通信协议的选择，功率/可靠性的妥协，很容易导航。我们的目的是通过开发网络分布式控制的研究生课程将这项研究与博士课程联系起来。
