Hybrid Traffic Dispersion and Network Densification Scheme for 5G Millimeterwave Wireless Networks

Abstract

Recent trends in research and scientific studies are represented in developing the wireless communication systems to achieve 5G networks with ultra-high reliability, ultra-low latency, high capacity, large amount of data transfer, massive connection density, while improving the quality of service (QoS). Achieving ultra-low latency is one of the fundamental goals for 5G wireless networks to enable new services and applications such as, virtual reality, live content streaming, automated vehicle control, internet of things (IoT) where machines and tools can be controlled remotely with extreme response, and many delay sensitive applications over the mobile network. This paper investigates hybrid strategy of traffic dispersion and network densification, which aims to split and transmit an arrival traffic over multiple different paths within the ultra-dense network. This improved the capacity of, and reduced the communication delay in, planned 5G-wireless network for urban area in Taiz city, Yemen. For our proposed 5G-wireless network there are 376 microcells, which operates using millimeter-Wave (mm-Wave) with the 73 GHz band, and used as providers for 274702 subscribers within the covered urban area of Taiz city. The planned 5G-network is carried out using OMNET++ and MATLAB simulation tools, hence the performance of this network is evaluated by key performance indicators (KPIs) such as average throughput, and communication delay. Based on the obtained results the amount of network throughput has reached a high value, up to 9 Gbps at each cell, with 88% probability that average one hop delay less than 0.5 ms.
