Context Management and Distribution Architecture Using Software-Defined Networking

This paper proposes an eHealth context management and distribution architecture with semantic features and designed for the Future Internet. A formal basis was used for managing both QoC (Quality of Context) and QoS (Quality of Service). Our approach was assessed in an experimental setting by using biomedical and environment sensors. The experiments showed that the context semantic processing detects anomalies or inconsistencies, generating consistent alerts. We observed that the SDN (Software-Defined Network) allows the context to be transported and delivered in accordance with the QoS context requirements. Therefore, our approach provides knowledge with fine granularity to assist health caregivers in making decisions.
