Cloud-based Web of Things: A Telemedicine Use Case

To fully exploit the capabilities of the Internet of Things (IoT), it is expected to assemble large-scale networks made of heterogeneous IoT devices (e.g., embedded systems, sensors, and actuators) and smart systems. These devices and systems should interact in a seamless fashion regardless of the underlying protocols. Yet, most of the actual IoT deployments are based on proprietary technologies and tightly coupled systems. To overcome application layer interoperability issues, the Web of Things (WoT) paradigm aims at making smart things an integral part of the Web and, thus, enabling them to interact through Web protocols, in accordance to Web standards. In this paper, we extend our system for WoT meant for associating to the geographically distributed IoT resources publically resolvable URL/URI. In particular, we propose in this work a HATEOAS-enabled mechanism to discover IoT resources available on an IoT node. This approach makes developers, and users alike, able to discover available resources within a node without knowing them beforehand. A use case is also described, in the context of telemedicine.
