Abstract

The invention provides a spatial network route planning method and a system thereof. The method comprises the following steps: spatial environment information is acquired based on a spacecraft sourcenode, a spacecraft target node and a pre-constructed spatial network environment autonomous sensing model; based on the spatial environment information, a spatial routing scheme is generated by adopting a pre-established spatial autonomous networking and routing planning model. This routing planning method introduces spatial awareness and artificial intelligence algorithms. The invention makes theroute planning method more feasible in space, makes up for the deficiency of adaptability and flexibility of the spatial route, improves the intelligence level and autonomous operation ability of satellites and spacecraft, introduces an artificial intelligence algorithm, saves a large amount of calculation time, and speeds up data processing.

Description

Technical field: [0001] The invention relates to the field of space networking and routing thereof, in particular to a space network routing planning method and system. Background technique: [0002] Routing in the space communication network is to find a path that can reach the destination address for the information to be transmitted, and ensure that the data is effectively transmitted from the source address to one (or more) destination addresses. It is the basis for the interconnection and intercommunication between different types of aircraft nodes and key. The routing algorithm of the space network is usually required to be simple, reliable, stable, and able to adapt to changes in network traffic and topology. However, due to the space communication network has the characteristics of long propagation distance, extended transmission time or variable delay, strong node mobility, intermittent link disconnection, dynamically variable network topology, poor communication q...
