基于拓扑控制的卫星网络路由优化
Routing optimization based on topology control in satellite network
摘要
Abstract
A new double-layer satellite network model for space networking was established and a routing algorithm based on topology control (TCRA) was proposed considering the advantages of low earth orbit and stationary earth orbit satellite networks. This model used virtual node strategy and satellite grouping idea, which regarded the coverage area of each low earth orbit satellite as a virtual node. The network took into account the influence of the polar area on the divi-sion of the satellite footprints, such that the upper management satellites can accurately acquire the topology of the lower satellites. Using the improved virtual node strategy, the time slices were superior to other network models in quantity, length and other aspects. Based on the network topology, stationary earth orbit satellites calculate routing for low earth orbit satellites, while low earth orbit satellites were responsible for forwarding data. The simulation results show that the routing algorithm is superior to other algorithms in average end-to-end delay and packet loss rate.关键词
