The rapid development of mobile communication technology has promoted the technological change of society. The fifth generation (5G) communication technology has become the focus of research in the field of communication technology. This paper aims to optimize the performance of the ship networking system based on 5G cellular network. To this end, it combines 5G cellular network and radio technology related theories, and conducts the simulation experiments on the communication system to compare the ET-MAC and TDMA protocols in terms of packet loss rate, time delay and throughput etc. The study found that the packet loss rate of ET-MAC is lower than that of TDMA, and the former has better performance; as the number of ships increases, the delay in ET-MAC is lower, but both protocols can realize the information transmission in a relatively short period of time; for a large amount of data, ET-MAC is more helpful to improve the transmission performance of the system. This study combines 5G technology with ship networking information technology, which provides theoretical support for the performance optimization of the ship networking systems.
