|Collaborative Processing in Sensor Networks|
| This proposal presents a career development plan for integrating research and education. The research component of this program focuses on the study of collaborative signal and information processing (CSIP) algorithms as well as the supporting computing models and protocols in sensor networks. The educational component is aimed at enhancing the newly created computer engineering program of the department through innovative curriculum development, active student mentoring, and by incorporating research findings into classroom teaching. The project consolidates research and educational efforts, responds to the unique challenges presented by sensor networks, and contributes significantly to the PI's career development.

| MU-FASHION is a research effort aimed at developing an agent-based infrastructure for multi-resolution, hierarchical, and collaborative signal processing in sensor networks. This infrastructure will include the following innovations: (1) an agent-based sensor fusion architecture that is network-centric as opposed to bring platform-centric; (2) a fault-tolerant, multi-resolution signal integration algorithm that provides real-time, progressively accurate results; (3) a graph-theorectic self-organizing algorithm for multi-tiered sensor networks; and (4) a next-generation lightweight real-time operating system. This work is led by Duke University, in partnership with the University of Tennessee at Knoxville, and Louisiana State University.

| The underwater sensor network has presented a lot of challenging problems, including the energy issue, the scalability issue, the reliability issue, and the real-time response issue. The limited underwater acoustic transmission channel and the slow propagation speed make these issues even harder to solve. Although it is difficult to meet all the objectives at the same time, we can provide performance evaluations and simulations that would suggest a near-optimal solution given certain constraints. In this project, we evaluate different computing paradigms to carry out distributed processing. We will also develop an underwater sensor network simulator (USNSim) using IAI's agent-based ad-hoc mobile network simulation technology. Evaluation metrics including cost, detection accuracy, response time, degree of fault tolerane, etc. This work is led by Intelligent Automation, Inc. (IAI), in partnership with the University of Tennessee at Knowville.

| Mobile sensor platforms that carry imaging, distancing, and wireless communication capabilities are assembled by the students. Image understanding algorithms to help the mobile sensor understand the environment. A group of these sensors can coordinate to better react to or reason about the real-world phenomena. Most of the existing sensor network testbeds are fixed. The few mobile testbeds either have limited processing capability that prevents them from running interesting and practical applications like target tracking, sensor deployment, and other mission-oriented tasks; or that they are too costly for group deployment. We will design and implement a mobile sensor network testbed that can provide sufficient processing capability for both 1-D signal processing and 2-D image processing with low low (<$500 each platform).

|ATR using Multispectral Imaging|
| University of Tennessee, in partnership with North Carolina State University, proposes multi-spectral and geometrical based automated target recognition - a research effort aimed at developing a "smart" target recognition system which takes advantage of both the multi-spectral and geometrical information available at different ranges from the target.

|Medical Imaging with Thermal Infrared|
| This is a research effort that helps define thermal infrared (TIR) imaging as a diagnostic tool in breast cancer detection, which can be used as a complementary modality to traditional mammography. This research includes the following innovations: (1) it first proposes a completely automated segmentation and detection algorithm to analyze TIR images of breast; (2) it develops an experimental plan to apply the proposed algorithm to both thermogram and mammogram taken from the same patient of cases including FP, FN, TP, and TN to get objective comparison of the sensitivity of these two imaging procedures in breast cancer detection. Testing images will be provided by Elliott Mastology Center at Baton Rough, LA, and Ville Marie Breast Cancer Center in Montreal, Canada.

|Image Processing and Optimization|
| Compared with all the other semiconductor imaging sensors, the charge-coupled-device (CCD) provides higher resolution, wider dynamic range, and higher sensitivity, with which conventional photography can not compete. However, CCD sensors also cost more. Some applications like medical imaging require both high resolution and large area, which makes the device even more expensive. How to achieve large area and high resolution, while at the same time remaining cost-effective is the mainly concern of this research.
