| 摘 要： | 具有星际链路的卫星网络将在今后发挥巨大的作用,而混合星座具有比单层星座更加优异的性能,双层星座GEO/LEO能够在物理上实现网络管理和业务的分离,便于对全网络的管理和集中式路由的实现。依据卫星网络运动的规律性,采用虚拟拓扑路由策略,在OPNET中对GEO/LEO双层星座进行了集中式路由的仿真;在定义链路权值时,除了传统上考虑的传播时延、排队时延外,还加上了地理因素的影响,使之更符合卫星网络的实际情况。

| Abstract: | Satellite networks with inter-satellite links will play an important role in the future, and a hybrid constellation performs bet- ter than a single layer constellation. Hybrid GEO/LEO constellation can separate network manage from traffic in physical layer, convenient to manage total network and operate central routing. Satellite networks run regularly in the space, so virtual topology routing strategy is adopted, and a central routing is simulated in the hybrid GEO/LEO constellation based on OPNET. Geographic factor are taken into account besides traditional propagation delay and queuing delay when defining link weight to accord practical satellite net- works. |
