In order to provide more collision avoidance information to ships that may encounter each other in dense sea areas, prevent collision events, and minimize channel data pressure, ensure network reliability and reduce latency, this paper proposes a regional protocol for local communications among maritime autonomous surface ships based on VDES (High Frequency Data Exchange System). Based on the theoretical foundation of the ship domain model in the field of ships, the area where collision danger exists is found by guiding the ship domain model, and this area is used as the routing flood area, and the routing request is limited to this area. The improved AODV (Ad hoc On-Demand Distance Vector) routing forwarding algorithm is used to establish a communication link between ships in the routing request area using real-time location information. This can exchange more information with ships located in the collision risk area to assist in collaborative obstacle avoidance and prevent accidents. At the same time, it effectively avoids network-wide routing flooding, avoids network congestion, and ensures network stability. Simulation analysis shows that this protocol is superior to AIS in terms of delivery rate and delay on the basis of realizing business functions. This will be beneficial for obstacle avoidance between encountering ships.
