Centralized and Decentralized Routing Solutions for Present and Future Space Information Networks

Space information networks (SINs) are pushing the boundaries of networking into near-Earth orbit and beyond. Nevertheless, harsh costly space context forces most risk-prone missions to be designed with minimal chance failure. The careful consideration routing protocols used connect fleet is by no means exception. Although decentralized SIN schemes have received attention research community, centralized approaches captivating industry, as these come tighter control enable troubleshooting valuable assets from a mission center on ground. In this article, we settle matter qualitatively quantitatively comparing both paradigms. We propose two novel schemes, evaluate their resulting performance against contact graph (CGR), state art. evaluation, computational effort, memory utilization, energy consumption taken figures merit. outcome provides compelling evidence that can safely, successfully, efficiently SINs up 10,000 daily contacts, while CGR better entrusted larger-scale deployments.
