摘要: |
LEO卫星网络能够提供全球覆盖,为任何地点的用户提供适时应用服务。然而由于LEO的高速运动,LEO卫星网络的网络拓扑一直处于动态变化的过程中。文中首先分析了在这种动态变化的网络环境中QoS路由面临的新问题,接着提出了解决这些问题的几点考虑。 |

Abstract: |
Low Earth Orbit (LEO) satellite networks can provide global service and support real-time applications to users regardless of the users' locations. However,due to the high mobility of these satellites, the network topology is highly dynamic. This paper first analyzes the new problems that we have to face about the QoS routing in the dynamic network. Then it gives several considerations to overcome these problems. |
