Improving QoS using Software-Defined Networking for Smart City (SDSC)

چکیده مقاله

Recently IoT, as one of the emerging and developing concepts, is rapidly evolving into other aspects such as smart cities and smart buildings, by enabling physical things and devices, including sensors, smartphones, and cameras, to interact .The exponential increase in the number of connected things has accelerated the development of new applications and services. These applications and services have new requirements, including dynamic management and control, and QoS that conventional network platforms are unable to meet. In other words, Software-Defined Networking (SDN) and Multi-access Edge Computing (MEC) can be a promising solution in IoT. SDN separates the control plane from the forwarding plane to enable more automated provisioning and policy-based management of network resources. With edge computing solutions we can enhance the data delivery ratio and processing power, decrease delays. So in this article, we propose and evaluate an SDNbased architecture for the smart city applications using the SDN and MEC concepts. Simulation results show that the proposed SDN-based architecture outperforms conventional architecture.
