Abstract: Satellite network is a novel wireless mobile communication network. Comparing with other communication networks, the unique properties of satellite network increase the difficulties to the network management. In the architecture of distributed management of the satellite network, an algorithm of management domains division is presented firstly based on the delay of links between the managed satellites and the sub-managers. The managed satellites select the sub-manager that has the shortest delay with it as its manager and the algorithm is simulated in the different constellations. Finally an improved algorithm is presented with a division factor δ based on the analysis of simulation results and it can increase the stability of the management domains.

摘要： 卫星组网作为一种新型的无线移动通信网络，与其他通信网络相比独有的特性增加了网络管理的难度。在分布式卫星组网管理结构下，首先提出了一种基于被管卫星与管理分站之间的通信链路时延的管理域划分算法，被管卫星选择时延最短的管理分站作为其管理者，并在不同星座结构下对该算法进行了仿真验证。最后通过分析仿真结果，对算法进行了改进，引入了划分因子δ提高了管理域的稳定性。
