Semantic Gateway as a Service Architecture for IoT Interoperability

Abstract

The Internet of Things (IoT) is set to occupy a substantial component of future Internet. The IoT connects sensors and devices that record physical observations to applications and services of the Internet [1]. As a successor to technologies such as RFID and Wireless Sensor Networks (WSN), the IoT has stumbled into vertical silos of proprietary systems, providing little or no interoperability with similar systems. As the IoT represents future state of the Internet, an intelligent and scalable architecture is required to provide connectivity between these silos, enabling discovery of physical sensors and interpretation of messages between the things. This paper proposes a gateway and Semantic Web enabled IoT architecture to provide interoperability between systems, which utilizes established communication and data standards. The Semantic Gateway as Service (SGS) allows translation between messaging protocols such as XMPP, CoAP and MQTT via a multi-protocol proxy architecture. Utilization of broadly accepted specifications such as W3C's Semantic Sensor Network (SSN) ontology for semantic annotations of sensor data provide semantic interoperability between messages and support semantic reasoning to obtain higher-level actionable knowledge from low-level sensor data.Note to the reviewers: Unlike traditional academic journal publications, IEEE IC has a preference to limit number of references, so we welcome any suggestions on removing references, especially if additional references are suggested for inclusions. We have also included some introductions to communication technologies and an overview on current IoT ecosystem to make this manuscript as self contained as possible, especially for IC's wider audience. However, if needed, some of these can be removed if we want to assume that readers will be; actionable suggestions and recommendations on these matters will be valuable.

“…9-16 also contribute to the healthcare IoT, nevertheless, these works only describe certain limited aspects of an IoT healthcare system, for example gateway design 11 , IoT and cloud 10 , security 14,15 ; and do not describe a complete architecture of an open source end-to-end healthcare IoT system.…”
