| 英文摘要: |
| Optimizing the power resources allocation method of low earth orbit (LEO) satellites to medium earth orbit (MEO) satellite’ links is a significant way to construct efficient satellite constellations for satellite communication. A game theory power allocation method based on remaining visible time (RVT) of LEO-MEO satellites is proposed. Firstly, one LEO-MEO satellite network is classified as a cluster in which the RVT of LEO satellites is modeled. Secondly, the cost function of RVT concerning the character of orbit and throughput in each LEO satellite is mainly designed, which gives greater punishment of utility value to LEO satellites with less RVT and is an essential part of the reasonable utility function applied in diverse motion scenes. Meanwhile, the existence of Nash equilibrium for the proposed utility function in game theory area is proved. Thirdly, an off cluster scheme for LEO satellites through the proposed threshold is raised to ensure the overall utility value of the whole LEO satellites in cluster. Finally, the performance improvement of the proposed algorithm to the baseline algorithm is verified through simulations in different scenarios. |
