Efficient, Robust RFID Stream Processing for Tracking and Monitoring

University of Massachusetts, Amherst

Recent advances in Radio Frequency Identification (RFID) technology and ubiquitous networking are facilitating the emergence of an information infrastructure that collects real-time data associated with physical objects and delivers high-value content to a variety of user communities. Emerging user communities include supply chain management, healthcare, postal services, to name just a new.

Data stream management is central to such an RFID-based information infrastructure---it allows the relevant information to be sifted out of the flood of RFID data immediately after it emerges. Despite recent advances in related areas such as relational stream processing and sensor data management, RFID data---inherently noisy data for identification of individual objects---raises many new questions. The significant mismatch between raw RFID data and meaningful, actionable information required by RFID applications requires complex processing beyond the capabilities of existing stream systems. The incomplete and noisy nature of RFID data further complicates such data-information translation. The volumes of data generated from large RFID deployments can also stress or overwhelm existing stream systems.

The goal of this research project is to design and develop an efficient, robust stream processing system that addresses the challenges posed by the data-information mismatch, incomplete and noisy data, and high data volumes, and enables real-time tracking and monitoring. This project has several main components.
