GEO/LEO卫星网络的数据传输与抗毁性技术
Research on data transmission and survivability technology of the GEO/LEO satellite network
摘要
Abstract
Aiming at the problem that Low Earth Orbit satellites have a low real-time performance in transmitting data to the ground,a data transmission and survivability technology based on the double-layer satellite network is proposed.In the method,the Geosynchronous Earth Orbit satellite network is used as the communication backbone network,which is responsible for the relaying and forwarding of the data in the satellite network.The low-earth satellite layer is responsible for data collection and auxiliary routing. Combining the advantages of Geosynchronous Earth Orbit and Low Earth Orbit satellites can realize the real-time transmission of Low Earth Orbit satellite data.The multi-path transmission strategy improves the survivability of the satellite network. The performance of the proposed method is analyzed in terms of throughput,transmission delay,delay jitter and packet loss rate.Under the attack environment,the data delivery capability of the network is studied. The data transmission method based on the multi-layer satellite can solve the single-layer low-earth satellite network in data transmission, and satisfy the requirement of multi-service real-time transmission.关键词
