This project focuses on an important kind of networked embedded systems called sensor networks. Such networks have become popular platforms for continuous sensing and analysis of physical environments, leading to a better understanding of natural phenomena, civil infrastructures, animal habitats, and other important scientific and engineering issues. The sensor data can also be used to improve environmental protection, infrastructure safety and energy efficiency, to name a few of the potential applications.
The ad-hoc and dynamic nature of networked embedded systems make their communication protocols complex. This research uses the methodology of continuous error monitoring for continued improvement of reliability after the deployment of sensor networks. The project builds a framework consisting of compiler-based tools and software techniques for the detection, diagnosis and correction of programming errors on sensor networks. The nature of the sensor-network applications requires the hardware components and software protocols to be small and resource-constrained. The project therefore makes resource efficiency one of the critical design criteria.
The success of this project should contribute substantially to the reliability of sensor networks whose potential applications are very broad. The project also engages a broad community of students in various disciplines, through Honor Seminars, special mentoring programs and undergraduate research opportunities such as Purdue's EPICS program (Engineering Projects in Community Services).
