Abstract

To overcome the problem about lacking space resource for our country, the integrated resource allocation management on heterogeneous space-based networks can break through the barrier of single service on a satellite system, which has become a hotspot in the space information network. This paper improves the SDN framework with three layers into a four-layer-framework based on heterogeneous space-based networks. Moreover, an integrated resource scheduling framework also with four layers is proposed to realize the management on services and resource, including the operations of defining unified service features, describing unified heterogeneous resource and constructing service-resource matching model. Meanwhile, a service-on-demand decoupling heterogeneous resource allocation algorithm is proposed to solve the coupling matching model. Simulation results show that the proposed algorithm has better performance in terms of resource utilization and convergence. Compared with the improved greedy algorithm, the resource utilization ratio of proposed algorithm is improved by 3.81%, 6.66%, 9.00%, 10.85%, 12.88%, 18.40%, 21.74%, 21.58%, 21.45% and 21.29%, meanwhile, the resource utilization ratio is increased by 28.86% on average. Therefore, the proposed algorithm has strong applicability on resource allocation in heterogeneous space-based networks.
