Abstract

Maturity of virtualization techniques and the success of rich cloud services have pushed the horizon of a new sophisticated and connected IoT systems over the Internet. However, provisioning, including managing, such systems is still static, and consequently, costly and time consuming. It is poorly suited to the dynamic criterion of such systems. In this paper, self-adaptive management procedures are proposed towards QoS maintaining at the middleware level of IoT systems. The design is based on concepts such as Network Function Virtualization (NFV) and its generalization, Software-defined Networks (SDN) and edge computing. A realistic use case is implemented for illustration and validation purposes. Prototype execution shows the self-adaptive capabilities of the approach to maintain operative QoS while facing unpredicted events such as fire detection.

Abstract

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.

Abstract

In the recent years, telecom and computer networks have witnessed new concepts and technologies through Network Function Virtualization (NFV) and Software-Defined Networking (SDN). SDN, which allows applications to have a control over the network, and NFV, which allows deploying network functions in virtualized environments, are two paradigms that are increasingly used for the Internet of Things (IoT). This Internet (IoT) brings the promise to interconnect billions of devices in the next few years rises several scientific challenges in particular those of the satisfaction of the quality of service (QoS) required by the IoT applications. In order to address this problem, we have identified two bottlenecks with respect to the QoS: the traversed networks and the intermediate entities that allows the application to interact with the IoT devices. In this paper, we first present an innovative vision of a “network function” with respect to their deployment and runtime environment. Then, we describe our general approach of a solution that consists in the dynamic, autonomous, and seamless deployment of QoS management mechanisms. We also describe the requirements for the implementation of such approach. Finally, we present a redirection mechanism, implemented as a network function, allowing the seamless control of the data path of a given middleware traffic. This mechanism is assessed through a use case related to vehicular transportation.

Abstract

The Internet of Things (IoT) paradigm is expected to bring ubiquitous intelligence through new applications in order to enhance living and other environments. Several research and standardization studies are now focused on the Middleware level of the underlying communication system. For this level, several challenges need to be considered, among them the Quality of Service (QoS) issue. The Autonomic Computing paradigm is now recognized as a promising approach to help communication and other systems to self-adapt when the context is changing. With the aim to promote the vision of an autonomic Middleware-level QoS management for IoT-based systems, this paper proposes a set of QoS-oriented mechanisms that can be dynamically executed at the Middleware level to correct QoS degradation. The benefits of the proposed mechanisms are also illustrated for a concrete case of Enhanced Living Environment.
