A Task-Oriented Routing Protocol for Sea-Air Cross-Domain Networks

Ocean College, Jiangsu University of Science and Technology , Zhenjiang 212000, China

摘要

摘要: 随着海洋和空中作业的日益增多, 海空跨域网络成为了实现有效通信的关键技术。这类网络由水下子网和水上子网构成, 为了充分利用资源, 多种不同的应用程序将共享相同的物理设施。在这种场景下, 不同的数据包共存于同一网络中, 需要差异化的传送策略来满足应用需求。然而, 现有的路由协议往往无法根据应用需求来提供个性化的服务, 针对该问题, 文中提出了一种面向任务的海空跨域网络路由协议, 协议根据任务类型的不同调整转发因子的计算方式, 进而根据为特定的任务类型选择最合适的下一跳节点。此外, 文中还在协议栈中增加了预处理层来完成异构网络之间的通信。文中使用NS3(Network Simulator 3)进行了仿真, 仿真结果表明, 与其他典型的协议相比, 文中所提的协议总是能根据任务的特定需求实现最优的传输策略。

Abstract: With the increasing frequency of maritime and aerial operations, sea-air cross-domain networks have become a pivotal technology for achieving effective communication. Comprising underwater and surface subnets, these networks aim to fully utilize resources, enabling multiple diverse applications to share the same physical infrastructure. In this scenario, different data packets coexist within the same network, requiring differentiated transmission strategies to meet application demands. However, existing routing protocols often fail to provide personalized services based on application requirements. To address this issue, this paper proposes a task-oriented routing protocol for sea-air cross-domain networks. The protocol adjusts the calculation method of forwarding factors based on the types of tasks, thereby selecting the most suitable next-hop node for specific task types. Furthermore, this paper introduces a preprocessing layer into the protocol stack to facilitate communication between heterogeneous networks. Simulation experiments conducted using NS3 demonstrate that, compared to other typical protocols, the proposed protocol consistently achieves optimal transmission strategies based on specific task requirements.
