Abstract-This paper presents the Smart Device specification to interface with remote labs. To encourage the broader sharing of remote labs, the Smart Device paradigm decouples the client from the server and provides well-defined interfaces between client and server. Such Smart Device services are exposed on the Internet and enable interoperability with client applications, other Smart Devices and external services (e.g. a booking service). This paper presents the extensible and platform-agnostic specification of the Smart Device services and internal functionalities. The Smart Device specification contains sufficient service metadata to enable the automatic generation of basic client applications. The specification is illustrated through an example and first implementations of the specification are presented.

“…In the case of HTTP/CoAP proxy, however, when the CoAP server finishes pushing notifications to the H/C proxy, the H/C proxy will have trouble delivering it to the registered client since it communicates with the client using HTTP but HTTP server does not have the ability to initiate a session. A remedy is to keep the HTTP client polling [10,11] the server whether there is a notification, but polling will incur much extra network traffic as Fig. 2 shows.…”

“…In the example, a dedicated connection is used for the CoAP observation relationship. In Step 1 the MCN issues, using HTTP long polling [29], a hanging HTTP GET request to the GW node. A hanging GET is used since the MCN wishes to observe the CoAP resource, that is, receive notifications when new data becomes available.…”

In this article, we propose a new architecture for wide area sensor and actuator networking. The architecture is based on combining two protocols being standardized by the Internet Engineering Task Force, REsource LOcation And Discovery (RELOAD) and Constrained Application Protocol (CoAP). To integrate CoAP and RELOAD, we introduce a CoAP application usage for RELOAD. The architecture provides a decentralized peer-to-peer rendezvous service for CoAP nodes in Wireless Sensor Networks (WSNs). Our architecture also enables a peer-to-peer federation of geographically distributed WSNs. This is supported by proxy nodes that are part of the WSN but also connect to a RELOAD overlay network via cellular Internet access. Due to the use of RELOAD, the system does not need to rely on centralized services such as DNS service discovery (DNS-SD) or central resource directories to discover sensors and resources. Other features of the architecture include integration to web, self-organization, scalability, and robustness. We evaluate the proposed architecture through simulations and real-life measurements, and compare its performance to a traditional client/server architecture.
