Context information and context-awareness are some of the drivers for the Internet-of-Things paradigm, whereas a well-stated and defined model is the key element of any context information system. An appropriate context model ensures that the information gathered by a context information system can be represented, manipulated and accessed, and even linked to different systems and domains.
This paper highlights the various modeling approaches used in different Internet-of-Things contexts and introduces our module designed especially for application in E-healthcare systems.
