摘要

网络编码在吞吐量、安全性和健壮性方面的好处对于诸如无线网状网络和点对点系统之类的大型网络来说是很好的理解。我们想知道在基于卫星的通信中是否可以实现类似的性能增强。我们的可行性研究重点是地球同步轨道卫星通信系统,包括再生有效载荷和多点波束卫星。此外,我们还考虑了具有多路径场景的LEO卫星星座。我们的分析表明,对于具有高动态和不可预测行为的新一代卫星系统,有几种网络编码技术值得考虑。

How feasible is network coding in current satellite systems?
The benefits of network coding in terms of throughput, security and robustness are well understood for a large class of networks, such as wireless mesh networks and peer-to-peer systems. We ask if similar performance enhancements can be attained in satellite based communications. Our feasibility study focuses on GEO satellite communication systems including regenerative payloads and multi spot-beam satellites. In addition, we consider LEO satellite constellations with multi-path scenarios. Our analysis reveals that several network coding techniques are worthy of consideration for new generation satellite systems with highly dynamic and unpredictable behavior.
