Abstract

Diversified interest in the low-cost broadband satellite has overgrown to support a wide range of services in the satellite network. There is a need to explore alternative parts of optical communication towards Light Fidelity (LiFi) to offload the overcrowded radio frequency segments and improve the overall throughput. Ad hoc networks are the most suitable solution to provide a non-trivial challenge towards system design due to efficiency and quality of service (QoS). Both contention and congestion issues can severely affect the performance of a multicast network where video streaming becomes part of the day-to-day life. In this paper, we present network congestion characterization related to LiFi and High Throughput Satellite (HTS) under the Ka-band modulation schemes during adverse weather conditions in the tropical region. The heterogeneous network performance presented in this paper comprehensively provides systematic information for Satellite communication (SatCom) & LiFi and optimization of throughput by reducing network contention ratio. The measurement results have shown that when Deep Packet Inspection (DPI) policy is applied, an improvement of 80.26% in the packet delivery ratio is achieved as compared when without a DPI policy. However, using an on-premise Software-defined-wide access network (SD-WAN) alone provides 58.20% improvement in the overall network system. As a result, DPI provides a well managed QoS approach to manage the entire hybrid network, mainly in the tropical environment region.

Summary

INTRODUCTION

The consistent improvement of broadband internet network alongside the continuous advances in voice and video has brought eagerness up in interactive multimedia services. Last-mile client device access requires a solution to switched out dynamically between different resolution, bitrate, and framerates depending on satellite bandwidth availability [3], [4] Focusing on these two hybrid network communication architectures, the study is made under the rainy and clear sky conditions to determine the network utilization and contention ratio. The meteorological impairments is a serious problem in satellite communication, mainly in a tropical region, VOLUME 8, 2020 which is generally described by heavy rainfall, especially at a high frequency For this reason, the paper investigates the entire heterogeneous network connectivity and throughput performance improvement, which has driven the adoption of network management tools. Based on the rain data obtained, on February, 14th2020, Bukit Jalil provides the highest and longest duration of the rain rate as compared with other rainy days and locations at Cyberjaya This provides better analysis data for both hybrid RF and LiFi network. The packet drop and the delay are further measured and recorded using the client-server iPerf command to further analyse the behaviour of the network mainly during the higher rain attenuation [21]
