“…The grey system fails to respond and hence perform effectively if the growth is tremendous. Due to this reason grey system is combined with Neural Network Model 11 to sustain the performance even if growth occurs. Dynamic load balancing scheme was proposed in Song et al 15 which focused to improve throughput of hybrid LiFi/WiFi networks.…”

“…The focus is to influence LiFi in high‐speed rail networks by adopting number of low cost LED in rail network. The passengers who are in need to use internet should sit below the LED lights and start to precede with their request queries 11 . The proposed mechanism in Figure 2 consists of LiFi and WiFi implemented in high‐speed trains, where the indoor connectivity is handled by LiFi during the day time i.e., when the lights are switched ON.…”

“…The handoff mechanism takes three inputs such as Serving LiFi AP, neighbor LiFi AP and neighbor WiFi AP. Signal to Interference Ratio measurement report is requested from these three access points and then provided to grey system model 11,15 . Now the received signal strength for three access points gives three original arrays as follows:

X_{i}^{false(0 false)} = false{x_{i}^{false(0 false)} false(1 false), x_{i}^{false(0 false)} false(2 false), x_{i}^{false(0 false)} false(3 false), . . . . false}, i = 1, 2, 3 ⋯ .

Summary Recent times witness heavy usage of high‐speed vehicles specially trains commuting long distances. Managing connectivity both indoor and outdoor for these vehicular networks is inevitable. Practically, the concept of wireless fidelity (WiFi) proves to be very fluctuating for the indoor users travelling in high‐speed vehicles as it operates under radio frequencies in the frequency spectrum, and handoff becomes mandatory as the user is mobile. With the introduction of light fidelity (LiFi), indoor connectivity between the mobile terminals is improved as the conversation is through light emitting diodes (LEDs) and photo detectors, which act as transmitters and receivers, respectively. Usage of LiFi in the high‐speed vehicular networks also nullifies the repercussions generated by using WiFi's highly radiated electro magnetic (EM) waves. The work proposes the use of LiFi in high‐speed rail networks for passengers streaming of videos. Travelers in train can access internet using LiFi, which uses ultra asymmetrically and symmetrically clipping optical (ASCO)–orthogonal frequency division multiplexing (OFDM) (UASCO‐OFDM) as its modulation technique. A proxy server is deployed to enhance video streaming. Furthermore, the travelers using internet need handoff in case of change in connectivity between access points (APs) of WiFi and LiFi for both outdoor and indoor, respectively. The work emphasizes on handoff based on the estimation of signal to interference ratio (SIR) followed by the combination of grey system. The performance analysis of the proposed system shows improvements in handoff probability, average delay, and spectral efficiency of modulation technique when compared to the existing literature.
