Dynamic Coordination For Distributed Planning With Limited Communication @ University of Virginia Main Campus
As is clear from the emergence of the Internet, the national electric power grid, and other large-scale network infrastructures, engineering systems today are increasingly reliant on distributed control authority and coordination between subsystems. Typically, coordination is achieved in engineering systems through the specification of ad hoc protocols for relatively well-defined (constrained) interactions between distributed systems. As information systems become more integrated into society, however, we find that existing protocols are not adequately tuned for new applications and/or unexpected situations. Though issues of decentralized control and planning are becoming more prevalent in the engineering systems we build today, there unfortunately appears to be little in the way of underlying guiding principles and theory for designing and operating such systems. Notions of game theory and decentralized control go only part way toward revealing the basic problems associated with distributed engineering systems, especially in situations where distributed agents/players/actors all recognize the same performance objective and would work together except for the problem of having little or no opportunities to coordinate their actions because of limited communication. In this project, the PI's goal is to derive an enhanced understanding of coordination without explicit communication by posing a new class of sequential decision processes, known as coordination processes, whose analysis will provide new theoretical insights and new algorithmic approaches in decentralized systems and distributed planning applications. The mathematical framework the PI team will investigate is rooted in the theory of controlled Markov processes and dynamic games, thus providing a firm foundation for new results, including new solution concepts and new algorithmic approaches for identifying optimal coordination strategies. The PI team will focus their efforts broadly on two subclasses of coordination problems: transient coordination processes where all actors seek to drive an underlying system to a terminal state with minimum cost; repeated play coordination processes where the objective is to learn optimal coordination strategies that tend to minimize the average cost perceived in repeated instances of a coordination problem. The PI team will evaluate their solution concepts and algorithmic procedures in the context of two illustrative applications, a robotic planning problem and an Internet traffic engineering problem, both of which require autonomous agents (actors) to coordinate without opportunities for explicit communication.
Broader Impact: This work will impact diverse research communities, including those for control theory, game theory, and decision sciences. The results should find application in diverse sectors of engineering and computer science, including the design of new MAC-layer protocols, the design of better conflict resolution algorithms in distributed collaboration tools and peer-to-peer applications, the design and control of transportation resource management systems, and in future sensor management systems.

Technology Based Evaluation of Classroom Learning @ University of Virginia Main Campus
This research will address the feasibility of enabling teachers at the high school and college levels to evaluate how well their students are learning via an automated analysis of data collected through technology-based instrumentation of their classrooms. The data will include audio/video collections on interactive class room behaviors, which are related to established performance markers. Results of data collections will be integrated into a DVD presentation that will produce feedback for the teacher for self-evaluation with the opportunity for self-improvement, or incorporation into guided coaching systems. The effort will build upon prior efforts from three different research communities: education, military intelligence, and Internet technology. This research will advance video processing that focuses on automated behavior pattern analysis related to a class room. It will also increase understanding of the relationship between previously developed manual class room observation metrics for helping teachers to improve and corresponding metrics gathered from an array of class room sensors. The conduct of this work will lead to identification of yet to be considered advances in the application of audio/video technology to classroom monitoring and teacher self improvement as well as the opening of innovative lines of research on classroom settings.
The proposed effort initiates a new and important research collaboration at the University of Virginia integrating the work of researchers who have been engaged in improving education at the Center for Advanced Study of Teaching and Learning and researchers who have been engaged in future applications of advanced wireless sensor technology at the Wireless Internet Center for Advanced Technology, an NSF sponsored Industry/University Cooperative Research Center. This collaboration is considered to be an important element in advancing the concept of technology-based class room evaluation. If successful, this effort will undoubtedly spawn a variety of opportunities for improvement of the initial concept and the corresponding development of new production systems.

This proposal seeks funding for the Wireless Internet Center for Advanced Technology (WICAT) sites at the Polytechnic Institute of NYU (lead), Auburn University, the University of Virginia, and the Virginia Polytechnic Institute and State University. Funding Requests for Fundamental Research are authorized by an NSF approved solicitation, NSF 10-601. The solicitation invites I/UCRCs to submit proposals for support of industry-defined fundamental research.
Increasing demand for video services on handheld and other wireless devices has made efficient exchange of video data using wireless devices a necessity. However the continual changes in user demand, network traffic and hardware of the wireless environment pose significant research challenges to achieving this goal. The proposed research seeks to address these challenges via a three pronged effort to explore wireless technologies able to adapt to changing communication system states. A test bed environment for the conduct of the proposed work that will provide system surveillance and cloud computing infrastructure will be provided by Cisco Systems.
Efficient and seamless use of video on wireless platforms in the emerging cloud computing environment will have major economic impact in virtually all economic sectors. Ubiquitous implementation and widespread adoption of these services will also create societal impact through the degree of communication it will enable. The proposed work has the potential to inform and define approaches to achieving this video content integration. The work has the potential to strengthen collaborative ties and link resources among the four participating center sites to further both research and education in this critical area.
