RESTful Web Services for the Internet of Things

In the coming years, the size and scope of the Internet will greatly increase as physical world devices (e.g., sensors and home appliances) are becoming smart enough to communicate and share data over the Internet—a phenomenon known as the Internet of Things (IoT). The problem of realizing the IoT is, however, how to effectively penetrate the devices into the existing Web. In this paper, we present Constrained Application Protocol (CoAP) and other key enabling technologies together with an end-to-end IP and RESTful Web Services based architecture for integrating physical world devices in constrained environments with the Web.
