In order to solve the issue of data transmission for maritime voluntary observation ships, an opportunistic network routing protocol (MVOS-RP) is proposed for the complicated maritime environment. The proposed protocol transmits data through the encounter between ships. A connected graph is constructed with the sending node as the vertex, and then the selection of the relay node is divided into three scenes by traversing the graph through the Breadth First Search (BFS) algorithm. We also use the ship’s Automatic identification System (AIS) information, such as the estimated time of arrival and the route of ships, to select the appropriate relay node. MVOS-RP protocol solves the transmission issue of opportunistic network in the environment of sparse nodes and poor communication link quality. Simulation is performed on Opportunistic Network Environment (ONE) platform. The results show that, compared with other protocols, the proposed protocol has a better balance in terms of data delivery rate, average latency and routing overhead. It is a reliable and efficient opportunistic network routing protocol.
