Abstract

Abstract:

To address the low resource allocation efficiency caused by the performance differences of heterogeneous links in low Earth orbit-geostationary Earth orbit hybrid satellite networks, a dynamic joint resource allocation optimization algorithm for low Earth orbit-geostationary Earth orbit hybrid satellite networks is proposed. This algorithm first comprehensively considers performance indicators such as satellite remaining service time, available bandwidth resources, and link latency, designing a multi-attribute weighted satellite link performance evaluation method tailored to service demands, enabling differentiated satellite selection for business access. Building on this foundation, with the goal of optimizing network spectral efficiency, the concept of bandwidth resource blocks is introduced. By setting satellite access load thresholds, a dynamic joint resource allocation optimization strategy based on access selection results is designed. Simulation analysis of the algorithm’s performance demonstrates that the proposed approach enables dynamic resource allocation based on service types, significantly improving the acceptance rate of various service requests while enhancing network spectral efficiency.

Key words: low Earth orbit-geostationary Earth orbit hybrid satellite network, access selection, resource allocation, joint optimization
