Abstract：Three new merged-reconstruction-based Inter-Layer Inter-Satellite Link(ILISL) establishment strategies are proposed to reduce the number of network topology reconfiguration and enhance the topology structure stability of the two-tier Low Earth Orbit (LEO)/Medium Earth Orbit (MEO) satellite networks. These proposed strategies decrease the number of the network topology reconfiguration by forcing reconstruction of all ILISL at the same time. Simulation results show that the number of the network topology reconfiguration can be reduced greatly with proposed strategies. Hence the topological stability of the LEO/MEO two-tier satellite networks can be improved with acceptable cost.
