Incremental aggregation of RFID data
Roberto De Virgilio, Pierpaolo Sugamiele, Riccardo Torlone · 2009
Radio Frequency Identification (RFID) technology plays a key role in supply chains and a challenging problem is the effective and efficient management of the enormous volume of data generated by such systems. In this paper, we propose a new framework for storing and querying a large amount of RFID data. The approach is based on a compression technique that allows a significant saving of space according to a suitable notion of aggregates over RFID data and a logical representation of these aggregates. We also propose an indexing technique for aggregates of RFID data that guarantees the efficient execution of an important class of queries. We finally present the architecture of a tool implementing our approach and demonstrate, with a number of experimental results made with this tool, the feasibility and effectiveness of the underlying techniques.
