Abstract
Recently, wireless data traffic has increased considerably because of the widespread consumption of ultra-high speed and large-capacity multimedia in the mobile media industry. Li-Fi technology, which can transmit information at a high speed using visible light, has attracted attention as a wireless local area network (WLAN). However, Li-Fi technology may face the problem of hidden nodes in the network topology. In this study, to address this problem, we performed simulations of the RTS-CTS algorithm in the Li-Fi MAC layer. The results of the simulation were used to propose the scope of the RTS-CTS algorithm. We evaluated a case in which the RTS-CTS algorithm is applied and one in which it is not. The simulation results indicated that the former case was advantageous over the latter one in dense network environments.
