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

Abstract

Sea-air cross-domain networks consist of underwater and surface subnets. In order to fully utilize resources, enable multiple applications to share the same physical infrastructure, and make different data packets coexist within the same network, differentiated transmission strategies are needed to meet application demands. However, existing routing protocols often fail to provide personalized services based on application requirements. To address this issue, a task-oriented routing protocol for sea-air cross-domain networks was proposed. The protocol adjusted 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, a preprocessing layer was added to the protocol to facilitate communication between heterogeneous networks. Simulation results show that compared to other typical protocols, the proposed protocol achieves optimal transmission strategies based on specific task requirements.
