Sensor networks have expanded their scope and capabilities, becoming a fundamental part of the Internet of Things (IoT). To be able to affront the interoperability needs that this rise brings, it is necessary to have a repository with standard interfaces and messages. This has been addressed through the creation of the Sensor Observation Service (SOS). However, after several years since its last update, many changes have occurred in the World Wide Web (WWW) and the Internet of Things (IoT). To meet these changes and renew the SOS, this article presents a SOS / REST over HTTP architecture that serves the networking of sensors and integrates a Constrained Application Protocol (CoAP) proxy that meets the Internet of Things (IoT) developments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
