Control node dynamic selection method in low-orbit constellation edge computing system

The invention relates to the field of low-orbit satellites, in particular to a control node dynamic selection method in a low-orbit constellation edge computing system. Comprising the following steps: after the whole constellation is divided into a plurality of satellite partitions, a control node in each partition discovers and maintains own virtual adjacent node information through message interaction; the control nodes in each area reach a consensus for the virtual topology information by using message interaction with the virtual adjacent nodes; and the control nodes in each region select consistent interval control nodes by using the same algorithm based on the virtual topology information, namely the control nodes in the low-orbit constellation edge computing system. The interval control node selection method adopted by the invention firstly depends on message transmission among control nodes in each area, so that the control nodes in each area are consistent with the virtual topology condition of the c
