Complex event processing for the Internet of Things and its applications

Abstract

In this paper, we present a distributed complex event processing (CEP) engine for Internet of Things and its applications. A CEP Engine combines information from a variety of sources. It looks for patterns in these event streams and then responds in real-time. Complex event processing is an effective mechanism to analyze object data, to reason sensing events, and to trigger responding actions for the intelligence of IoT application. A building controlled by a building automation system (BAS) is often referred to as an intelligent building, smart building, or a smart home. BAS core functionality keeps building climate within a specified range, lights rooms based on an occupancy schedule, monitors performance and device failures in all systems, and provides malfunction alarms to building engineering contractors and maintenance staff. The advantages of employing a distributed CEP engine for smart building are demonstrated.
