An Efficient Model for Horizontal Slicing in 5G Network using Practical Simulations

The telecommunication field has seen unprecedented growth in the last decade, which has led to the release of several generations committed to satisfying users by increasing the data rate and reducing the latency, especially in the 5G network. With fully commercialized 5G networks that have already been launched in many countries, software-defined networking (SDN) and network function virtualization (NFV) facilitate the implementation of network slicing (NS). SDN and NFV serve as the basis for NS, allowing efficient use of both physical and virtual resources. This paper analyses and proposes an efficient model that utilizes all of the available resources of the 5G network. In doing so, a set of optimizations have been done on the proposed network model, where we experimented with varying the radio link throughput quality and the number of users. The evaluation has proved that using the horizontal slicing (HS), all the virtual networks (VNOs) are independently satisfied according to their service layer agreement (SLA) contracts and whatever the radio conditions.
