The Research on Complex Event Processing Method of Internet of Things

Event processing is the key part of the middleware of Internet of Things. There are some challenges in complex event processing for event cloud in internet of things, such as heterogeneous, massive data, distributed event processing and the occurrence time of each event is unknown. In order to resolve the challenges, a complex event processing method of internet of things event cloud is proposed in this paper. This is based on Service Oriented Architecture (SOA), and design an efficient Complex Event Processing (CEP) that based on query plan, which supports imprecise timestamps and resolves the problem of disorder event. The experimental study shows that this method can process disorder event and the performance of the model and approach is better than normal methods when processing large-scale event cloud in internet of things.
