Priority-aware Situation Awareness (ASAP): While Moore's law has held true for predicting the growth of processing power, the volume of data that applications are called upon to handle is growing similarly, if not faster. The enormous amount of sensing data continually generated for real-time analysis coupled with the inherent dynamism and computationally demanding nature, make situation awareness a challenging CPS domain for networked systems. To face this challenge, we propose to transition from the sense-fuse-actuate characterization of these applications to a new sense-prioritize-fuse-actuate characterization. Adding the prioritize step will help not only in an effective use of the available resources, but also in providing real-time guarantees in the presence of data deluge. Developing an integrated fusion and prioritization architecture for situation awareness is the focus of this ongoing research.

| Distributed fusion support (DFuse): DFuse is an architectural framework for dynamic application-specified data fusion in sensor networks. It bridges an important abstraction gap for developing advanced fusion applications that takes into account the dynamic nature of applications and sensor networks. Elements of the DFuse architecture include a fusion API, a distributed role assignment algorithm that dynamically adapts the placement of the application task graph on the network, and an abstraction migration facility that aids such dynamic role assignment. Experimental evaluations show that the API has low overhead, and simulation results show that the role assignment algorithm significantly increases the network lifetime over static placement. This project is in its mature stage, and our current focus here is now to integrate fusion with prioritization algorithms as part of the ASAP project. | |
| RF2ID: Reliable Framework for Radio Frequency Identification: It is a middleware system for RFID devices. Current RFID based middleware faces several challenges that require a scalable solution to handle the very large volume of data generated by RFID devices. The inherent unreliable nature of the RFID devices complicates the problem more. The focus of our work is to provide a scalable solution that handles the unreliability at middleware level. |
