Abstract:
With global mobile traffic doubling every 18 months along with the massive increase in unique data users across digital platforms during the Covid-19 pandemic, the world's demand for high-speed connectivity continues to increase every second. The Covid-19 pandemic has transformed the global workforce with remote working arrangements, embracing new platforms, subsequently increasing the requirement for reliable, quality, ubiquitous high speed data connectedness everywhere. 5th Generation (5G) mobile communication technology provides an effective solution, modernizing network infrastructure, efficiently providing reliable high bandwidth capacity for massive data growth and ultra-low latency, making delays virtually impossible to perceive. This means elevating reality even further with fiber-like speeds for everyone, everywhere. 5G network slicing makes it possible for services to own dedicated portions of the 5G network with guaranteed performance for their particular need. These virtual networks allow for a service like IoT, at industrial scale, making society more sustainable and increasing resource efficiency. Our paper proposes a model for 5G network slice creation that meets industry verticals service QoS requirements which are critical to service adoption. A software emulation is utilized to guide the design and evaluation of our proposed model. Simulated results show QoS guarantees are met for the reviewed service requirements in varying network conditions. |
