Abstract:
As the growth and the spread of Internet of Things (IoT), various context-aware applications, which determine their behaviors based on the recognized context, are widely studied and developed. To develop such applications, an application programmer has to understand every sensor's specification, e.g., access method (i.e., how to get a current value), for handling all the necessary sensors. Moreover, even some sensors are the same types, e.g., temperature sensors, they may have different units of values, hence, the unification of each sensor's unit may be required. These make some inexperienced programmers hard to develop context-aware applications. In this paper, we present a novel middleware named Virtualized Sensor System (VSS), which provides some features for application programmers as follows: (i) provides unified methods to access every sensor in the system without any knowledge of their specifications, and (ii) can create new software-defined sensors by composing of some hardware sensors. To help to create a new software-defined sensor, we present a new markup language, Virtual Sensor Markup Language (VSML). Our proposed system VSS and markup language VSML can make the developments of the context-aware applications using various sensors easy even if an application programmer is inexperienced in them.
