Ontological Approach for Context Aware Modeling and Reasoning in Sensor Network

With the advent of Mobile and Pervasive computing, the applications and services are required to adapt dynamically according to changing environmental situations. Context aware system senses the change in computational surroundings and dynamically adapts their behaviour to environmental change without any user intervention. Using contexts such as time, location people and activity, WSNs know which information is significant to transmit. It helps to retrieve the system information easily. In this paper, we propose a context ontology model for sensor network environment. We execute queries on our ontology using rules defined in SWRL and infer those rules by rule engine. The proposed model has the provision of context reasoning, reusability and sharing of knowledge.
