Abstract
A significant increase is expected in video and multimedia traffic in Beyond 5G networks. The inclusion of a huge number of IoT nodes in Beyond 5G networks further complicates the design of such networks. These futuristic networks are expected to deal with this increased traffic and number of nodes while ensuring that network delays do not exceed a certain threshold. In such networks, Quality of Service (QoS) provisioning has become vital, not only to guarantee certain key performance indicators but also to improve user experience. This paper proposes a hybrid approach for end-to-end QoS provisioning, involving both clients and controllers to address these challenges. Each client tries to satisfy its own access QoS requirements by choosing optimal access device(s) and makes decisions based on locally available view. Controllers are then responsible for finding optimal paths in the core network to satisfy client core QoS requirements. Experimental results show that the proposed approach provides better QoS guarantees than several other access device selection and routing schemes.
Highlights
With the auctioning and roll-out of 5G networks in several countries across Europe, the United States, and Asia, the research community has started to lay out plans for Beyond 5G (B5G) networks
B5G networks will have to deal with a massive increase in the number of connected Internet of Things (IoT) devices and manifolds increase in multimedia traffic
Whereas in C-Received Signal Strength Indicator (RSSI), a node initially selects an AP based on the maximum available RSSI, but does not continuously scan for other available APs after connection
Summary
With the auctioning and roll-out of 5G networks in several countries across Europe, the United States, and Asia, the research community has started to lay out plans for Beyond 5G (B5G) networks. B5G networks, among other requirements, aim to provide higher peak data rates of up to 10 terabits per second, universal connection, low latency, reliability, higher energy efficiency, universal connectivity, ubiquitous intelligence, and native security. In addition to the increased number of devices, a continual increase in demand for mobile data traffic is expected due to web applications, real-time streaming, and IoT applications [3]. B5G networks will have to deal with a massive increase in the number of connected IoT devices and manifolds increase in multimedia traffic. To ensure a certain level of network quality for such traffic and guarantee a certain user experience, providing Quality of Service (QoS) guarantees will be very important in next-generation wireless networks, such as higher data rates, seamless mobility, ultra-low latency, high reliability, and energy efficiency [3]
