In this letter, we present the analytical investigation of the non-orthogonal multiple access (NOMA) assisted underwater visible light communication (UWVLC) system. The proposed system can cater to the needs such as low latency, high reliability and high data rate underwater multicasting to the sensor nodes. The UWVLC link is characterized by Exponential-Generalized Gamma (EGG) distribution. In particular, we derive the exact closed-form expressions of average bit error rate (BER) and ergodic capacity for underwater NOMA users. Further to understand the impact of the underwater scenario over the system performance, the analysis is carried out for parameters such as air bubble levels, gradient temperature and salinity level of the water. The obtained results validate the feasibility of the proposed system model.
