| 摘 要： | 针对网络拓扑动态变化和路由多重选择等问题，空间节点按其属性划分为3个不同的物理簇，各簇可按需要进行下一级子簇的划分，建立了基于多层分簇架构的动态网络拓扑演化模型，从MEO独立运行、GEO和MEO协同运行2个方面研究了导航系统的路由策略。设计了基于簇管理者、簇首和簇成员的三级信息传输与分发机制。通过分簇和子簇间边界节点的设置，实现了簇间的拓扑变化相互屏蔽、独立的组网路由策略和子簇间的信息交互，减小了网络管理和路由计算的复杂度。

| Abstract: | A dynamic network topology evolution model was established based on multilayered clusters. Moreover, the routing policy was studied from the two aspects of MEO working independently and GEO/MEO working collaboratively. The three-level information transmission and distribution mechanism was proposed via employing cluster manager, cluster head and cluster member. Finally, through the cluster division and boundary nodes selection among the sub-clusters, the scheme achieves the inter-cluster topology change shielded from each other, independent networking routing and sub-cluster information exchange, as well as a low network management complexity and routing calculations. |
