Using Environmental Contexts to Model Restrictions on Sensor Capabilities

Abstract:
Cyber-Physical Systems (CPS) incorporate the physical and digital worlds via sensors and actuators. The system devices may be heterogeneous, distributed in space, and mobile. This leads to new challenges in the design of applications that should utilize the full potential of the system. As devices are unreliable and may be arbitrarily moving away from locations of interest, there is a continuous necessity to replace them with alternatives during runtime. The handling of this task by the application programmer is error-prone and complex because the system might be heterogeneous and different sensors and actuators possibly possess varying means to observe and influence the environment. Therefore, a capability model has to be employed on the operating system level which provides a holistic view of the different devices. In this regard, an environmental context model has to be supplied as the devices' capabilities may be restricted depending on the contexts they are located in. This paper presents an environmental context model based on an abstract sensor capability model. In conjunction, the models provide a description of sensors concerning their ability to observe properties of physical objects of interest within their particular environmental contexts. The effect of contexts on the spatial interpretability of sensor measurements is therefore made explicit. Corresponding inferences are made with respect to the localization of physical objects or phenomena of interest.
