Research Objectives

Impact of Network Function Virtualization on the Quality of Service of an IoT Based Sensor Network

The Wireless Sensor Network is an invaluable resource and a key data provider for the Internet of Things (IoT) paradigm which is an inter-connected world full of physical and virtual devices capable of providing services over the Internet. As it is expected that thousands of different objects belonging to different contexts will be accessed remotely, the use of current WSNs is inefficient and leads to redundant deployments. Therefore, more cost effective and flexible solution is needed to enable the real time and easy deployment for heterogeneous networks.

Network Function Virtualization (NFV) technology is the solution for reducing cost and accelerating service deployment for network operators by decoupling network functions from dedicated hardware devices and moving them to virtual servers. Several applications can benefit from the virtualization technology as this approach aims to support applications with different requirements in terms of nodes and communication functionalities and to utilize the available communication resources in an efficient and cost effective manner.

The aim of this research is to explore how the Network Function Virtualization (NFV) would influence the Quality of Service (QoS) of the Internet of Things (IoT) based sensor networks for vehicular communication. The research will be focused on the vehicular networks related to traffic congestion management, one of the main big city problems, which could be addressed with the virtualization technology. The intelligent management of traffic might help to cope with the volume of traffic without the need for laying new roads or increasing the number of park spaces. For IoT applications, the reliable, trusted and best connectivity is essential for smart objects. So, solutions for Quality of Service for any IoT application need to be provided to deliver the right solutions.
