It is becoming increasingly crucial to integrate pattern matching functionality over live and archived event streams with hybrid event queries for various complex event processing(CEP) applications. As existing Stream Processing Engine(SPE) and DBMS alone can not accommodate hybrid event queries, we investigate system integration issues and scheduling algorithm optimizations of hybrid event processing...
Complex event processing has been extensively applied in areas such as RFID tracking for supply chain management, fluctuation detection in stock trading, real-time intrusion detection in network monitoring,etc. Most existing research works focus on specification, formalization and evaluation of single-object oriented complex event processing. In this paper, we investigate complex event processing...
CEP(complex event processing) over RFID (radio frequency identification) data streams has become a new paradigm recently. Existing NFA (non-deterministic finite automata) based RFID event detection techniques assume single granularity RFID data (e.g., only item-level RFID readings) in the stream. In this paper, we consider CEP problems over multiple granularities RFID data streams (e.g., item-level,...
