Parallel Multi-hop Routing Protocol for 5G Backhauling Network Using HPC Platform

Abstract

Fifth generation (5G) systems are considered as the future of telecommunications and data processing. 5G systems are envisaged to increase current network capacity by 1000-fold. In addition to increasing spectral efficiency and utilizing wider bandwidths, ultra network densification with wireless small cells is considered a significant capacity-enhancing method for meeting the ever-increasing demand of 5G data traffic requirements. The enormous amounts of data traffic generated in inter-small-cell 5G backhaul networks require efficient routing protocols to speed up the routing decisions, while ensuring high data rates, low latency, and low power consumption requirements. Therefore, a parallel routing protocol is proposed to speed up routing decisions in 5G backhaul networks, using high performance computing (HPC). We explore the efficiency of utilizing HPC to manage and speed up the parallel routing protocol using different communication network sizes. Our numerical results indicate that our HPC implementation achieves a routing speed-up of 37x for large network size (2048).
