Performance Evaluation of CRC-16 in Indoor Visible Light Communication (VLC) Against Jamming Attack

Visible light communication (VLC) is the optical wireless communication technology that allow to transmit large amount of data. Aside from high speed and broadband properties, the VLC still requires appropriate protections against jamming attack due to the public space lighting interference and possibly adversary existences. Therefore, we proposed implementation of crc-16 for error detection in indoor VLC based on IEEE standard 802.15.7. The simulation analysis focuses in physical and MAC layer. The test parameters that used in this research are signal to noise ratio (SNR), signal to interference plus noise and ratio (SINR), bit error rate (BER), and delay. Simulation results show that the VLC system is still vulnerable to interference and jamming attacks that detected by CRC-16. This is indicated by number of received CRC which not equal to 0. In addition, SINR value obtained at 6.32 dB compared to the SNR value of 15.50 dB, it can be seen that there is a decrease in system performance. For the jamming attack simulation, we used various of jamming probabilities. This helps in identifying potential vulnerabilities and fixes that required to increase system resilience.
