The Internet of Things is a promising implementation approach to the vision of ubiquitous computing. However, "things" in the IoT are not always collaborative, cooperative or predictable. Things may interfere with each other or may be programmed erroneously. They may fail or cause other things to fail. This paper addresses issues of safety in the IoT with a special focus on a main source of concerns - devices. We analyze safety issues in IoT and propose a domain independent safety ontology to be used by all stake-holders of an IoT system to express their safety concerns in the form of knowledge. We also present a device description language intended for use by device manufacturers to describe device safety. Finally, we present a sensor domain ontology that assists in providing explicit hints to the IoT system about the relationships between sensors and actuators. Such hints help significantly in empowering the devices themselves to proactively participate in enhancing the overall system safety. © 2011 ACM.
