Malaysia High-speed railway (MyHSR) communications will become a key
feature supported by intelligent transportation communication systems under the
4th Industrial Revolution for On-The-Move (OTM) internet access. Congestion in
the radio spectrum, big data bandwidth networking issues and requirement of
smaller antenna sizes simulating greater interest in the underutilized Ka
frequency band. However, transmission at these shorter wavelengths is greatly
influenced by signal noise resulting in signal attenuation and decreased link
availability.
The main innovation is to improve the throughput and bandwidth load balancing
between Ka-band High Throughput Satellite (HTS) space communication and
heterogeneous hybrid Light Fidelity (Li-Fi) in tropic. In line with this, the objective
is proposing of an approach of a Ka-band satellite signal attenuation expectation.
The strategy also considering disabilities experienced during climate elements
for tropical area and high portability situation on the High-Speed Rail (HSR)
application.
The second part of the thesis compromises network integration, by enhancing
the throughput and handover performance on both Satcom and Li-Fi. The
process involves designing the indoor hybrid Li-Fi channel model where there is
an exploration on the feasibility of utilizing a half breed HTS satellite and Li-Fi
network for OTM application. In the third part, this thesis takes advance steps by
focusing in achieving better satellite-Li-Fi backhaul network integration for both
On-The-Pause and On-The-Move developments.
The methods focused on this approach, supported with a novel experimental,
Proof of Concept (PoC) and validation of a heterogeneous satellite-Li-Fi network.
This is done by managing the bandwidth and throughput capacity under the
Deep Packet Inspection (DPI) model.
Finally, an analysis led, a reliable channel performance in tropical area for
mobility application has been identify with an improvement of 19.52 % in overall
receiving Packet Loss Ratio (PLR) including enhancement on the network
throughput by 67.24% while carrying out DPI solution during unfavorable climate
condition. |
