Abstract:  Along with the continuous extension of application and the emerging of task significance, space-based networks and communication satellite constellation play more and more important roles in future network communications. The technology progresses of space-based resource management are important for assurance of instantaneity and high efficiency of operational load. In this paper, the status quo and business characteristics of space-based network are analyzed. According to the function and characteristics of resource management system of space-based information network, the dynamic resource management technology was studied, including implementation scenario, function reconstruction and resource allocation. For realtime resource allocation, an adaptive distributed resource allocation method was proposed based on first price sealed-bid (FPSB) auction game, and the corresponding allocation scheme was designed. Finally, through the simulation of space-based network scenarios, the advantages of the proposed method in improving the utilization rate of resources and system operation efficiency were proved.
