This project focuses on an important kind of networked embedded systemscalled sensor networks. Such networks have become popular platformsfor continuous sensing and analysis of physical environments, leading toa 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 fewof the potential applications.The ad-hoc and dynamic nature of networked embeddedsystems make their communication protocols complex.This research uses the methodology of continuous error monitoring for continued improvementof reliability after the deployment of sensor networks.The project builds a framework consisting of compiler-based tools and softwaretechniques for the detection, diagnosis and correction ofprogramming errors on sensor networks.The nature of the sensor-network applications requires the hardware componentsand software protocols to be small and resource-constrained.The project therefore makes resource efficiencyone of the critical design criteria.The success of this project should contribute substantially tothe reliability of sensor networks whose potential applications are very broad.The project also engages a broad communityof students in various disciplines, through Honor Seminars,special mentoring programs and undergraduate research opportunitiessuch as Purdue's EPICS program (Engineering Projects in Community Services).
