摘要
近年来,利用不同轨道高度卫星的各自优势组成多层卫星网络逐渐成为热门研究,文章针对多业务条件下GEO/LEO双层卫星网络中的接入与切换策略进行了深入分析,提出了一种参数加权平均的接入策略,并将其应用在一种改进的基于业务量的双层卫星网络接入与切换策略中。实验仿真表明,该改进策略能够在一定程度上改善不同级别用户的通信质量,更加合理地利用双层卫星信道资源。
In recent years,the use of their respective advantages in different altitude satellite of multi-layer satellite network has gradually become hot research,aiming at more business under the condition of GEO/LEO double-layer satellite network access and switching strategy carried on the thorough analysis,this paper puts forward a parameter of the weighted average access strategy and its application in an improved double satellite network access and switching strategy based on volume.The experimental simulation shows that the improved strategy can improve the communication quality of users of different levels to a certain extent,and make more reasonable use of the resources of the two-layer satellite channel.
