Abstract

Internet of Things (IoT) technologies have evolved rapidly during the last decade, and many architecture types have been proposed for distributed and interconnected systems. However, most systems are implemented following fragmented approaches for specific application domains, introducing difficulties in providing unified solutions. However, the unification of solutions is an important feature from an IoT perspective. In this paper, we present an IoT platform that supports multiple application layer communication protocols (Representational State Transfer (REST)/HyperText Transfer Protocol (HTTP), Message Queuing Telemetry Transport (MQTT), Advanced Message Queuing Protocol (AMQP), Constrained Application Protocol (CoAP), and Websockets) and that is composed of open-source frameworks (RabbitMQ, Ponte, OM2M, and RDF4J). We have explored a back-end system that interoperates with the various frameworks and offers a single approach for user-access control on IoT data streams and micro-services. The proposed platform is evaluated using its containerized version, being easily deployable on the vast majority of modern computing infrastructures. Its design promotes service reusability and follows a marketplace architecture, so that the creation of interoperable IoT ecosystems with active contributors is enabled. All the platform’s features are analyzed, and we discuss the results of experiments, with the multiple communication protocols being tested when used interchangeably for transferring data. Developing unified solutions using such a platform is of interest to users and developers as they can test and evaluate local instances or even complex applications composed of their own IoT resources before releasing a production version to the marketplace.

Highlights

The rapid growth in computer communication technology and the application of networked system solutions into every area of our daily lives as well as the increasing number of devices that use such networks create many prospects for subsystem interconnections, provisioning a new generation of cyber-physical services widely referred to as the Internet Things (IoT) [1]

The approach is compared to Ponte, an open-source framework that we examine, and experiments illustrate reduced energy consumption when using Representational State Transfer (REST) HTTP and

Summary

Introduction

The rapid growth in computer communication technology and the application of networked system solutions into every area of our daily lives as well as the increasing number of devices that use such networks create many prospects for subsystem interconnections, provisioning a new generation of cyber-physical services widely referred to as the Internet Things (IoT) [1]. Many ontologies and data models have been proposed regarding the IoT domain for devices, data, and IoT resources in general, e.g., the IoT-Lite [21], which is tailored to sensor networks; the SAREF (Smart Appliances REFerence) ontology [22], which describes smart appliances and was defined by collaborating with the industrial sector; the Ontology for Wearables Data Interoperability [23], which can be used for ambient assisted living applications; and IoT-A [24] Such semantic descriptions can help with the discoverability of devices and services and with their automated reconfigurability and management. Ontologies and semantics are not always incorporated in the available IoT platforms
