Abstract

The invention discloses a task-oriented spatial information network resource management method, for mainly solving the problem of a lower utilization rate of spatial information network resources due to time variation characteristics in the prior art. The implementation process is as follows: 1, initializing a network node, dividing a network planning period into multiple equilong time slots, and calculating a visible condition between each nodes in each time slot; 2, constructing a resource time variation diagram to represent network resources, and constructing a resource time variation conflict diagram to represent the conflict of the resources in the network; 3, solving an independent set of the resource time variation conflict diagram; 4, solving a non-conflict resource time variation diagram according to the independent set; and 5, solving multiple commodity stream problems in the non-conflict resource time variation diagram to obtain an optimal resource distribution scheme. By adopting the task-oriented spatial information network resource management method disclosed by the invention, the conflict of resource shortage and business development is relieved, the complexity of resource management in a spatial information network is reduced, and a technical support is provided for system research and resource management of the spatial information network, so that the task-oriented spatial information network resource management method can be applied to the distribution of spatial information network resources.

Description

technical field

[0001] The invention belongs to the technical field of space information, and mainly relates to a space information network resource management method, which can be used in the task planning and scheduling process of the space information network. Background technique

[0002] The space information network is an important infrastructure in my country and an important platform to support earth observation, ocean navigation, emergency rescue, navigation and positioning, air transportation, and aerospace measurement and control. However, due to the high cost of space information network facilities such as satellites and ground stations, and the long satellite launch cycle, my country's space information network has long faced a situation of resource shortage and short supply. In order to alleviate the contradiction between resource shortage and business development, it is very important to study efficient resource management methods suitable for spatial informat...
