Client Based Access Layer QoS Provisioning in Beyond 5G IoT Networks

Abstract

Modern end-devices have an ever-increasing battery and processing power, a better view of the access layer, and a better understanding of the application and device-specific requirements. With the amount of expected increase in the number of nodes and data traffic in Beyond 5G networks, ensuring Quality of Service (QoS) guarantees would become very challenging. IoT networks are made up of heterogeneous IoT devices, where each device might have very different QoS requirements. The QoS parameters for the access network might also differ from the core network. This paper proposes a client-based optimal access device selection mechanism for QoS provisioning in heterogeneous IoT networks, while also reducing the load on network devices. Network devices are still responsible for QoS provisioning in the core network. Simulation-based experimental results for indoor hybrid Light Fidelity (LiFi) and Wireless Fidelity (WiFi) networks show that our proposed access point selection technique outperforms current commonly used access point selection strategies.
