【摘要】：为了弥补单层卫星网络的缺点,综合各单层卫星网络的优点,形成优势互补,为用户提供更好的服务质量,混合卫星网络应运而生.针对不同的卫星接入算法对卫星的服务质量的影响各不相同,重点研究设计更好的混合卫星网络和卫星接入算法.在分析GEO、MEO、LEO和HEO卫星网络各自的特点的基础上,综合其性能的好坏和设计实现的难易程度,设计并提出5 GEO+66 LEO的双层卫星网络及多QoS约束的卫星接入算法.最后通过仿真分析,验证该算法的正确性.
[Abstract]:In order to make up for the shortcomings of single-layer satellite networks and integrate the advantages of single-layer satellite networks to form complementary advantages and provide better quality of service for users, hybrid satellite networks emerge as the times require.Because different satellite access algorithms have different effects on satellite quality of service, better hybrid satellite networks and satellite access algorithms are studied and designed.Based on the analysis of the characteristics of GEOOOOLEO and HEO satellite networks, combining their performance and the degree of difficulty in design and implementation, a 5 GEO 66 LEO double-layer satellite network and a multi-#en3# constrained satellite access algorithm are designed and proposed.Finally, the correctness of the algorithm is verified by simulation analysis.
