In view of the problem that the security of network management is easily decreased by the center node troubles in the traditional satellite network management mechanism based on hierarchical-clustering structure, a novel scheme is proposed to meet the needs of the security cluster head, which supports the fast switching between formal and backup cluster head, and then a relevant new priority-based selecting algorithm is proposed for the formal and backup head selecting the formal cluster head and the backup cluster head through cluster members negotiating and priority calculating in consideration of communication ingredients comprehensively in satellite cluster such as accessibility, delay and reliability. The results of simulation indicate that the scheme can not only replace the failure cluster head and recover the cluster in very short time, but also minimize management cost of the cluster head.
