Abstract:

Fast routing technology of space access networks is studied in case of dynamic network topology, big transmission delay and a topologybased routing method of rapid construction techniques is According to the analysis about predictable movement characteristics of space access point, space access network is organized by means of WMN（Wireless Mesh Networks) to transmit data. Through WMN structural analysis, we designed a mobile backbone topology construction algorithm for space access network, which spread flooding information only among backbone nodes and reduced the amount of control and routing packets. So this algorithm is able to quickly construct routing information and improve the efficiency of routing establishment.

Key words: space network, wireless mesh network（WMN）, access network, backbone topology construction
