论文摘要
来自太空的互联网访问享有文艺复兴，因为大型构成中的卫星不再是虚构的。在其他挑战和其他挑战之外，受到功率和计算复杂性约束的网络容量是这类网络的主要目标。这项工作研究网络编码在动态变化的网络条件下。引入并采用了广义无环网络的概念，用于促进被认为是循环网络的线性 - 媒体网络代码的生成。其中几种网络编码方案的性能，其中包括已知的静态网络代码，通过STK模拟来评估一群传达卫星的群，从概念上讲，这是基于虹膜系统的。随着时间的推移，描述了网络拓扑的先验知识，描述了新的网络编码方法，其目的是更好地应对网络的随时间变化，动态行为。可以证明，在所有情况下，与我们的示例网络有关，与提出的方法相比，静态网络代码表现不佳。此外，提出了用于识别最合适的编码方法的有效测试。
Internet access from space enjoys renaissance as satellites in Mega-Constellations is no longer fictitious. Network capacity, subject to power and computational complexity constraints among other challenges, is a major goal in this type of networks. This work studies Network Coding in the presence of dynamically changing network conditions. The notion of generalized acyclic network is introduced and employed for promoting the generation of linear-multicast network code for what is considered to be a cyclic network. The performance of several network coding schemes, among these is the known static network code, is evaluated by a STK simulation for a swarm of communicating satellites, conceptually based on the Iridium system. Exploiting the prior knowledge of the networks topology over time, new network coding approaches are described, whose aim is to better cope with the time-varying, dynamic behavior of the network. It is demonstrated that in all cases, pertaining to our example network, static network codes under-perform compared to the presented approach. In addition, an efficient test for identifying the most appropriate coding approach is presented.
