| 摘 要： | 随着空间技术的发展,航天器网络化的趋势不断增强。航天器不仅需要将数据实时地传输到地面,而且需要与其他航天器实现信息共享。通过建设LEO卫星网,容易实现航天器的数据传输与共享,但是航天器的网络接入是研究难点之一。如果针对不同系统采用不同的接入方法,将增加接入的复杂度。通过采用区域路由方法,提出一种通用的接入方法,不仅简化了航天器卫星网络的接入,也简化卫星网络系统的设计,实现了接入方法与网络设计的适当分离。计算机模拟表明该方法的可行性。 |

| Abstract: | With the advance of space technology,network has become a trend for spacecraft. Spacecraft needs not only transfer data to the ground,but also share the information with each other.By building the LEO satellite network,it is easy for spacecraft to transfer and share data.However the network access method is one of challenges of the LEO satellite network.If different access methods are designed for different LEO systems,that will increase the complexity of access methods.A unified access method was proposed by using the area-routing method.It will not only simplify the access method of spacecraft,and the design of satellite network system.In addition,the access method will be independent from the satellite network design.The computer simulation result shows the feasibility of the access method. |
