Abstract

The invention provides an allocation method and device for satellite resources in a space information network, and relates to the technical field of satellite detection. The method comprises the steps that traffic data of multiple information source satellites in a current time slot is counted; historical traffic data of each information source satellite is acquired; traffic data in a target time slot is predicted according to the counted traffic data in the current time slot and the acquired historical traffic data to obtain prediction information, wherein the prediction information is used for predicting the queue length of a to-be-transmitted data queue of each information source satellite in the target time slot; service resources are pre-allocated according to service arrival of the prediction information to the target time slot, so that each information source satellite transmits the data according to the pre-allocated service resources, wherein the service resources comprise transmission power. Accordingly, the technical problem that in the prior art, the service resources cannot be reasonably allocated when the service resources are allocated is solved.

Description

technical field [0001] The invention relates to the technical field of satellite detection, in particular to a method and device for allocating satellite resources in a space information network. Background technique [0002] With the development of the space network, the demand for satellite communication of multimedia services is also increasing, for example, image services in typhoon monitoring. Therefore, how to design an appropriate cooperation mechanism to achieve efficient network resource allocation, maximize network utility, and minimize power consumption and delay is very important. [0003] In the prior art, when network resource allocation is performed, the traffic data of N time slots in the future cannot be predicted, which may result in data backlog and transmission power not properly allocated. Contents of the invention [0004] The purpose of the present invention is to provide a method and device for allocating satellite resources in a space information ...
