Context Awareness Technology Based on Ontology Mechanism for Sensor Networks
Biao Dong, Jinhui Chen · 2016
This paper presents a semantic-oriented approach for architecting sensor networks applications using ontology mechanism.Considering the validity and the timeliness which are necessary for sensor networks knowledge sharing and reusing, a common and extensible context ontology model is defined to describe the related concepts and their relationships.A context awareness process model is proposed to support process decomposition and knowledge reasoning.A matching algorithm is designed to detect instance constraints.The analysis indicates that the approach effectively realizes knowledge sharing, reuse and reasoning for context awareness applications in sensor networks.
