Abstract: Space information network is an intelligent system constituted by information systems of land, sea, air and space. An algorithm of management domain division was proposed to meet the needs of scalability in network management for space information network. An organization model of management was designed. Analytic Hierarchy Process (AHP) was used to select sub-management station, and then appropriate management domains could be formed. In domain maintenance phase, the function of sub-management station was migrated by mobile Agents. Dynamical maintaining mechanisms like domain merger/partition, reaffiliation and adaptive adjustment of information update period were also designed. The overhead and time spent in division as well as in data collecting for management were analyzed through simulations. The experimental results show the proposed algorithm of management domain division is suitable for space information network.
