Abstract

The main problems of current cellular networks illustrating high delay and traffic congestion relate to their network inflexibility and incorporated control and data planes. However, the prerequisites of 5G cellular systems are low delay, high throughput, low congestion at the core cellular networks, and seamless mobility and fast handover. To alleviate aforementioned problems we propose a 3-Tier Software-Defined Networking (SDN) architecture combined with a novel OpenFlow (OF) switch, which includes a User Rate-Perceived (URP) protocol and a Macrocell/Femtocell Information Base (MFIB). Our simulations prove that proposed mechanisms bring numerous benefits such as low delay, high throughput, low cost, and seamless mobility and fast handover to 5G cellular networks and high Dense Networks, which are called DenseNets.
