基于WMN的空间接入网络骨干拓扑构造技术

针对空间接入网络在网络拓扑动态变化、传输延迟大等情况下的快速路由问题，提出了基于拓扑构造技术的快速路由方法；空间接入网络通过多跳无线中继接入空间核心网络，根据空间接入点运动可预测的特点，提出基于无线网状网（WMN：Wireless Mesh Networks ）的空间接入网络结构；通过空间接入网络WMN的结构分析，设计了移动骨干拓扑构造算法。该算法只对骨干节点进行泛洪传播，从而减少了控制和路由数据包的数量，能快速构造路由信息，提高了路由建立的效率。

Backbone Topology Construction Method in Space Access Network Based on WMN

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.
