Abstract

The invention provides a routing method and device of an airport communication network. The method comprises the following steps: sending a first RREQ packet to at least one third node, wherein the first RREQ packet comprises an identifier of a second node, thereby enabling the third node to send the second RREQ packet to the second node; receiving first RREP packets sent by at least one third node, wherein each first RREP packet comprises the path congestion degree, and the path congestion degree is the congestion degree of a corresponding path when the first node sends the service data to the second node; selecting the path corresponding to the first RREP packet with the minimum path congestion degree to send the service data to the second node. Through the method provided by the invention, the congestion degree of each path to the second node is comprehensively considered at the first node, the path with the low congestion degree is selected to sent the service data, the packet lossrate and the communication delay of the service data transmission in the airport communication network are reduced, and then the reliability of the service data transmission is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a routing method and device for an air-to-air communication network. Background technique [0002] The airport communication network is a heterogeneous hybrid network composed of various spacecraft and near-space vehicles, which has great value in global remote sensing, information transmission or real-time monitoring. [0003] Routing technology is one of the key technologies of the airport communication network, and it is the basis and guarantee for the reliable transmission of the airport communication network. In the air-to-air communication network, due to the constant movement of nodes such as air-to-air aircraft, drones, and ground mobile terminals, the network topology changes dynamically. At present, the air-to-air communication network directly uses the on-demand plane distance vector Routing protocol (Ad hoc On-demand Distance Vector Routing, AODV) f...
