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.
