A Modular Framework for Dynamic QoS Management at the Middleware Level of the IoT: Application to a OneM2M Compliant IoT Platform

The Internet of things (IoT) has evolved exceptionally in recent years; enabling a large number of heterogeneous devices to be interconnected to users via the Internet. This new concept promises in a few years to interconnect billions of devices, which will generate many challenges on the infrastructure supporting these communications. One of these challenges is the satisfaction of the different QoS requirements of the applications. To address this challenge, we identified two bottlenecks with respect to the QoS, which are the networks and the intermediate entities (i.e. middleware) allowing the applications to interact with the devices. In this paper, we propose a modular framework to ensure the QoS of applications at the middleware-level through QoS-oriented mechanisms deployed dynamically and autonomously on the middleware entities. The benefits of this framework are presented through test scenarios in the vehicular transportation domain.
