Although much of the work has been done until today to realize the Internet of Things (IoT) into practice, most of the work focuses on resource-constrained nodes, rather than linking the existing embedded systems to the IoT network. In this paper, we propose the uID-CoAP architecture, a new architecture designed to host IoT services on common embedded systems, like usual consumer appliances. As they often need to provide a number of sophisticated functions compared to simple sensor nodes, we combine the constrained application protocol (CoAP) with the ubiquitous ID (uID) architecture. The latter plays a crucial role for keeping the knowledge and data required for practical complex IoT services. In addition, we provide a software framework for embedded appliance nodes, designed to reduce the burden of embedded appliance manufacturers by providing an intuitive, consistent, and easy-to-use APL Based on this idea, our framework provides functions to build RESTful services in addition to the low-level communication API. We have evaluated our system through a case-study, and showed that our framework can be used effectively to implement practical IoT applications over existing embedded systems with a small programming effort.
