Design and implementation of VDES Link Layer protocol applied to intelligent vessels

In recent years, intelligent vessels have become a new hot issue in the international maritime field. As a next-generation maritime dedicated mobile communication system, VDES can meet the communication needs of intelligent vessels. According to the VDES protocol stack, the function of the VDES data link layer is analyzed, the VDES link layer protocol signaling procedures and its interfaces are designed, and the VDES link layer function is developed on the Linux platform by using the C language. The testing environment of VDES DLL protocol is built to verify the feasibility of the protocol. The design and implementation of the protocol provide a reliable transmission method for the communication of intelligent vessels, and give a reference for the development of VDES system.
