Embodiment Construction

[0076] In order to better understand the contents of the present invention, an example is given here.

[0077] 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:

[0078] 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;

[0079] 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;

[0080] S3, initialize the visible low-orbit ...

Abstract

The invention discloses a method for dynamic scheduling of satellite resources based on disassembly structure and pheromone deposition, which includes the following steps: taking satellite resources, channel resources and time slot resources as scheduling objects, and taking time window, satellite energy consumption, channel quantity, Constrained by conditions such as ground user priority and communication burstiness, establish a system resource scheduling model and a low-orbit satellite resource scheduling model; judge whether the task set is an empty set, if it is an empty set, the task scheduling ends, and the optimal resource is output Scheduling result; otherwise, randomly select a task in the task set to determine whether there is a low-orbit satellite within the visible range, and if so, select a low-orbit satellite within the visible range for resource scheduling; otherwise, the task transmission fails . The resource scheduling model provided by the present invention is more suitable for resource scheduling of low-orbit satellites under the condition of large-scale dense networking, and has the characteristics of simple control, strong compatibility, low hardware requirements, and easy programming and realization.

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, ...
