Embodiment Construction

[0074] In order to better understand the contents of the present invention, an example is given here.

[0075] This embodiment discloses a method for dynamic scheduling of satellite resources based on disassembly structure and pheromone deposition. figure 1 The flow chart of this method comprises the following steps:

[0076] S1, taking satellite resources, channel resources, and time slot resources as resource scheduling objects, and constraining time window constraints, satellite energy consumption constraints, channel quantity constraints, ground user priorities, and communication bursts, etc., to establish a system resource scheduling model ;A time window contains several time slots;

[0077] S2. On the basis of the system resource scheduling model, a low-orbit satellite resource scheduling model is established with the goal of ground mission service quality and the total energy consumption of the low-orbit satellite system;

[0078] S3, initialize the visible low-orbit ...

Abstract

The invention discloses a satellite resource dynamic scheduling method based on solution set construction and pheromone deposition. The method comprises the following steps of taking satellite resources, channel resources and time slot resources as scheduling objects, and taking conditions such as a time window, satellite energy consumption, the number of channels, the priority of ground users andcommunication burstiness as constraints; establishing a system resource scheduling model and a low-orbit satellite resource scheduling model; judging whether the task set is an empty set or not, if so, ending task scheduling, and outputting an optimal resource scheduling result; otherwise, randomly selecting one task in the task set, judging whether a low-orbit satellite exists in the visual range or not, and if so, selecting one low-orbit satellite in the visual range for resource scheduling; otherwise, task transmission fails. The resource scheduling model provided by the invention is moresuitable for low-orbit satellite resource scheduling under a large-scale dense networking condition, and has the characteristics of simple control, strong compatibility, low hardware requirement, easiness in programming realization and the like.

Description

technical field [0001] The invention relates to the technical field of satellite communication network, in particular to a method for dynamic scheduling of satellite resources based on disassembly structure and pheromone deposition. Background technique [0002] With the gradual deepening of space exploration, satellite Internet has been deployed at home and abroad. In this field, foreign countries started earlier and have matured. Representative satellite systems include OneWeb, O3b, Starlink, etc. At present, for the first time in China, the construction of satellite Internet has been included in the category of "new infrastructure", and it has been upgraded to a national strategic project. Representative satellite systems include Hongyan constellation, Xingyun project, Hongyun project, Tianxiang constellation, etc. As an important part of the satellite Internet, the low-orbit satellite system has the characteristics of wide coverage, low latency, broadband, and low cost, ...
