Topology Virtualization and Dynamics Shielding Method for LEO Satellite Networks
Virtual Node (VN) method is widely adopted to handle satellite network
topological dynamics. However, conventional VN method is insufficient when
earth rotation and inter-plane phase difference are considered. An improved VN
method based on Celestial Sphere Division is proposed to overcome the defects
of the conventional method. An optimized inter-satellite link connecting mode
is derived to achieve maximal available links. The optimal VN division solution
and addressing scheme are designed to generate a nearly static virtual network
and solve the asynchronous switches caused by inter-plane phase difference.
Comparison results demonstrate the advantages of proposed method.Comment: 5 pages, 8 figures and 2 table
