Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0038] As mentioned in the background technology, the routing decision of the micro-nano satellite network in the prior art is mainly solved by the shortest path algorithm, but it is easy to cause some key links to be congested, and when multi-service path allocation, it needs to go through multiple iterations, the calculation is heavy, the timeliness is low, and the throughput is low.

[0039] Therefore, in order to solve the problems in the prior art, this application proposes a routing m...

Abstract

The invention discloses a routing method for a micro-nano-satellite network, by building a neural network model on each micro-nano-satellite network in the micro-nano-satellite network, and then training the neural network model through randomly generated training data packets , and then make routing decisions in the satellite network based on the trained neural network model, use the trained neural network model instead of the routing algorithm, simplify the routing calculation process to a simple input-output mapping, reduce the forwarding delay, and avoid calculation time Multiple iterations increase the network throughput, and each micro-nano-satellite regularly maintains its own neural network model. When the topology of the micro-nano-satellite network changes, the neural network model is retrained to improve the routing Applicability of the method to micro-nanosatellite networks.

Description

technical field [0001] The invention belongs to the field of satellite technology, and in particular relates to a routing method for a micro-nano satellite network. Background technique [0002] Micro-nano satellites refer to satellites with a mass of less than 10 kilograms and practical functions. They have the advantages of small size, low power consumption, short development cycle, formation and networking, and many complex space tasks at a lower cost. [0003] With the development of the space-ground integrated network and space missions, the demand for micro-nano satellite networking has become more and more urgent. Micro-nano satellites are low-orbit satellites. Rapid changes put forward special requirements for the routing mechanism in the network. In addition, the orbit of micro-nano satellites is low, which is vulnerable to various interferences, and the quality of inter-satellite links will change unpredictablely. [0004] The prior art usually uses the shortest p...
