Situation Aware IoT Service Coordination Using the Event Driven SOA Paradigm
Internet of Things (IoT) technology demands a complex, lightweight distributed architecture with numerous diverse components, including end devices and applications adapted for specific contexts. This paper proposes a situation aware IoT services coordination platform based on the event driven service oriented architecture (SOA) paradigm. Focus is placed on the design of an event driven, service oriented IoT services coordination platform, for which we present a situational event definition language (SEDL) an automaton based situational event detection algorithm, and a situational event driven service coordination behavior model, which is based on an extended event condition action trigger mechanism. Moreover, we propose a reliable real time data distribution model to support the effective dispatching sensory data between information providers and consumers, which is based on the grid quorum mechanism to organize those brokers into a grid overlay network to facilitate the asynchronous communication in a large scale, distributed, and loosely coupled IoT applications environment. We also illustrate the various illustrations for IoT services coordination and alarming disposal process of coal mine safety monitoring and control automation scenarios, and also report the measurement and analysis of the platform's performance.
