The rapidly developing field of optical wireless communication (OWC) technologies may be advantageous to radio frequency wireless communications in some applications. It is believed to be a viable remedy for reducing spectrum congestion and increasing system capacity in the next generation of 5G communication networks. Before OWC may be used in current and future communication systems, more study and development are required. When building a routing protocol for Underwater Wireless Sensor Networks (UWSNs) with limited energy resources, it is important to take into account an efficient method that can intelligently use energy, extending the network's lifespan. Both load balancing and energy usage are critical for a network's extended lifespan. This problem can be resolved by implementing sink mobility into sensor networks, which balances energy consumption among nodes while also protecting node energy. Multiple mobile sink architecture based energy efficient routing protocol (MSEERP), a revolutionary protocol for UWSNs, is proposed in this research. To solve the problem of connectivity gaps and rapidly gather data from sensor nodes, multiple mobile sinks are used. Comprehensive simulations are used to evaluate the effectiveness of the suggested approach, and the outcomes are contrasted with the GEDAR routing protocol.
