An eHealth Context Management and Distribution Approach in AAL Environments

This paper proposes an architecture for managing and distributing context information from an AAL (Ambient Assisted Living) environment to the cloud. The architecture, with semantic features, includes the processing of the sensed data using QoC (Quality of Context) parameters and data transport using SDN (Software-defined Networking). The experiments showed that the semantic context processing allows accurate assessment of the QoC context and the SDN flexibility allows the context to be delivered in a way to provide differentiated quality data.
