IEEE 1451.0-based Web of Thing (WoT) Ontology

Internet of Things (IoT) ecosystems are highly heterogeneous regarding smart sensors/devices, connectivity, communication protocols, data formats, and platforms. The major challenges of IoT ecosystems are fragmentation or disintegration and cross-domain interoperability. The Web of Things (WoT) integrates the IoT with Web technologies to address these IoT challenges. Semantic WoT (SWoT) integrates the WoT with Semantic Web technologies to achieve semantic interoperability of IoT ecosystems. Aiming to promote semantic communication, thus achieving semantic interoperability of the IEEE 1451.0based sensor networks for IoT applications, this paper introduces the IEEE 1451.0-based WoT ontology. An IEEE 1451.0-based WoT thing model is developed based on the combination of the IoT thing capability model and the World Wide Web Consortium (W3C) WoT thing model. The IEEE 1451.0-based WoT thing model consists of identification and context, behaviors, properties and data schema, security, time synchronization and protocol bindings for IEEE 1451 WoT Things – e.g., network-capable application processors (NCAP), application (APP), transducer interface modules (TIM), and smart transducers (sensors and/or actuators). A WoT thing description (TD) example of an IEEE 1451.0-based smart sensor is provided in the paper to verify the developed IEEE 1451.0-based WoT ontology.
