摘　　要：文中将容忍延迟网络(Delay Tolerant Network,DTN)应用于船舶通信,提出了一种基于长短时记忆网络(Long Short-Term Memory,LSTM)模型的动态转发路由协议LSTM-DRA(Dynamic Distribution Routing Algorithm Based on LSTM Model),该协议通过比较相遇船舶的预计行驶轨迹来为消息选择最优的中继节点,并使用多副本的策略实现消息的动态转发。同时,采取了拥塞控制策略,以降低网络拥塞。仿真结果表明,LSTM-DRA在提高送达率和降低路由开销等方面具有较高的性能,可实现可靠、低成本的消息传输。This paper applies Delay Tolerant Network(DTN)to ship communication,and proposes a dynamic forwarding routing protocol based on the Long Short-Term Memory model(LSTM-DRA).The protocol selects the optimal relay node for the message by comparing the estimated trajectory of the encountering ships,and uses a multi-copy strategy to realize the dynamic forwarding of the message.At the same time,a congestion control strategy has been adopted to reduce network congestion.Simulation results show that the proposed LSTM-DRA has better performance in improving delivery rate and reducing routing overhead.It can achieve reliable and low-cost message transmission.
