特别是在农村地区，并不总是有高速但高成本的数据通信基础设施。在这样的条件下，基于存储-携带-转发的消息在现有车辆网络上中继是作为延迟和中断容忍网络（DTN）的大数据递送的有前途的方法。在本文中，反映了一个真实的例子在印度尼西亚的情况下，我们认为DTN消息传递的情况下，相邻的岛屿只连接渡船。消息的源节点和目的节点是固定的，位于边缘岛屿。信息通过每个岛屿的汽车和公共汽车以及岛屿之间的渡轮传递。我们适应我们以前提出的路由协议的多岛的情况下进行了一些修改，并评估其有效性在两种情况下的交付方向。在这个新提出的版本，即自适应喷雾和跳距离协议（A-SnHD），二进制喷雾转发重复使用时，消息到达每个岛屿，并严格使用基于跳距离的转发，以防止不必要的传输到错误的岛屿。仿真结果表明，A-SnHD优于流行病和PRoPHETV 2的总发送消息的大小和开销比。
Especially in rural areas, a high-speed but high-cost data communication infrastructure is not always available. In such conditions, a store-carry-and-forward-based message relaying over existing vehicle networks is a promising approach to delivery of large data as delay and disruption tolerant networking (DTN). In this paper, reflecting a real example situation in Indonesia, we consider DTN message delivery scenarios over multiple islands where adjacent islands are connected only by ferry boat. The source and destination nodes of messages are stationary and located marginal islands. Messages are relayed by cars and buses in each island and by ferries between islands. We adapt our previously proposed routing protocol to the multiple-island scenarios with some modification and evaluate its effectiveness in two cases of delivery direction. In this newly proposed version, namely adaptive-spray and hop-distance protocol (A-SnHD), the binary-spray forwarding is repeatedly used when a message reaches each island, and the hop distance-based forwarding is strictly used to prevent unnecessary transmission to wrong islands. Simulation results show that A-SnHD outperforms Epidemic and PRoPHETV2 regarding the total size of delivered messages and the overhead ratio.
