A multi-dimensional ontology-based IoT resource model

Nowadays researches related to resource management and representation of IoT (Internet of Things) emphasize on making identify regulation or describing device working principle. However they could not represent dynamic feature and multi-dimensional feature of interaction. This paper propose a multi-dimensional ontology-based IoT resource model to solve above defects. For resource management, searching and reasoning, this model divides resource into 4 key concepts: general situation, variable feature, function and enforce. Then this paper classify resource into 5 dimensions. Experimental result shows that when IoT resource contains time feature, location feature and priority feature, resource model works well to accomplish management and searching task. In addition, this model lays a foundation for service model, which is in upper layer of resource model.
