Architecting Semantics-based Publish/Subscribe Applications for the Internet of Things

This paper presents a semantics-based approach for architecting the internet of things(IoT) applications using publish/subscribe(Pub/Sub) mechanism. Considering the features of openness and integration which are necessary for reducing the technical threshold for the development of the IoT and ensuring the large-scale distributed deployment, IoT application environment based on Web(AEW) is proposed in IoT applications. Service subscription center(SSC) is proposed to provide a rules-based dynamic situational reasoning service and an execution service. The analysis indicates that the approach effectively realizes knowledge publishing, reasoning and distributed deployment for semantics-based Pub/Sub applications in IoT.
