Optimizing Data Transmission for Deep Space A Comprehensive Overview and Research Trends of Licklider Transmission Protocol

Sincethe advent of the space exploration era, not only simple satellite communication but also communication distances such as Earth-Mars are getting longer and longer, and more space exploration technologies are being developed, so the technical requirements for deep space communication networks are increasing. Existing deep space communication networks have used DTN (Delay/Disruption Tolerant Network), a delay/disruption tolerant network for stable data transmission, as a core internetworking technology due to long link delay and link asymmetry. In this paper, we introduce the concept of LTP (Licklider Transmission Protocol), a core data transmission protocol as one of the convergence layer protocols of DTN and investigate recent research trends.
