Development of a user-oriented iot middleware architecture based on users’ context data

Abstract

How to manage the connections of things efficiently with heterogeneous things is one of the important issues for IoT middleware development. Many researches have been focused on this issue but still no one accepted as the common model in the IoT environment. In this sense, we aim to develop a new IoT middleware architecture containing simple key-value model based and no-model based context-awareness function. The suggested middleware represents the context data without strictly defined data structure. Rather, it processes the context more focusing on the other technical aspects. We build the middleware architecture based on the basic structure of GSN (Global Sensor Networks). Also, by adapting no-model based context representation method suggested by Habit, we added the context-awareness function to the GSN. Through the middleware, many heterogeneous things not integrated on the standard structure can be managed effectively. We expect the suggested middleware can provide a flexible solution in current IoT development situation.
