Visible light communication (VLC) is a new paradigm that could revolutionise the future of wireless communication. In VLC, information is transmitted through modulating the visible light spectrum (400–700 nm) that is used for illumination. Analytical and experimental work has shown the potential of VLC to provide high-speed data communication with the added advantage of improved energy efficiency and communication security/privacy. VLC is still in the early phase of research. There are fewer review articles published on this topic mostly addressing the physical layer research. Unlike other reviews, this article gives a system prespective of VLC along with the survey on existing literature and potential challenges toward the implementation and integration of VLC.

Waterfilling Algorithm

ABSTRAKPeningkatan terhadap kebutuhan akses data membuat Visible Light Communication (VLC) menjadi alternatif media transmisi nirkabel yang efisien. Namun berdasarkan performansinya, VLC memiliki permasalahan data rate yang tidak merata diterima oleh User Equipment (UE). Dalam mengatasi permasalahan tersebut, penelitian ini menerapkan alokasi daya kirim dengan algoritma waterfilling yang mampu memberikan keadilan data rate setiap UE berdasarkan nilai kanal. Penelitian ini menggunakan kanal Line Of Sight (LOS) dengan 3 skenario berbeda. Kami menggunakan parameter validasi untuk mengukur setiap kinerja dengan nilai Signal Noise Ratio (SNR), data rate, fairness index dan efisiensi energi. Dari hasil simulasi menggunakan algoritma waterfilling, kami memperoleh nilai fairness index untuk data rate sebesar 100% namun tidak memiliki efisiensi daya. Dengan memodifikasi algorima waterfilling, terjadi penurunan fairness index, SNR serta data rate, tapi memberikan efisiensi energi LED hingga 9%. Dengan demikan, daya yang dipancarkan oleh LED memiliki lifetime yang lebih panjang dengan modified waterfilling.Kata kunci: VLC, Power Allocation, Waterfilling, Fairness. ABSTRACTThe increase in the need for data access makes Visible Light Communication (VLC) an alternative wireless transmission medium that is efficient. However, based on its performance, VLC has a data rate problem that is not evenly accepted by User Equipment (UE). In overcoming this problem, this study applies power allocation with waterfilling algorithm that is able to provide fair data rate for each UE based on channel value. This study uses the Line Of Sight (LOS) channel with 3 different scenarios. We use validation parameters to measure each performance using the Signal Noise Ratio (SNR) value, data rate, fairness index and energy efficiency. From the results of simulation using the waterfilling algorithm, we obtain a fairness index value for the data rate of 100% but does not have a power efficiency. By modifying the waterfilling algorithm, there is a decrease in the fairness index, SNR and data rate, but provide LED energy efficiency of up to 9%. Thus, the power emitted by the LED has a longer lifetime with modified waterfilling algorithm.Keywords: VLC, Power Allocation, Waterfilling, Fairness.
