Online Pattern Aggregation over RFID Data Streams

摘要：

Complex events are very useful in radio frequency identification (RFID) applications. Even though many techniques have been proposed to de tect RFID complex event instances online, they do not support online pattern aggregation operations. In this paper, we present an online pattern aggregation algorithm, named RFID_PAQ. RFID_PAQ divides a sliding window into sev eral sub-windows and computes its aggregation value from those of its sub windows. Based on the distribution characteristics of RFID data streams, we design different mapping functions to dispatch events to related sub-windows. Finally, our extensive experiments demonstrate that RFID_PAQ is effective and efficient.
