TL;DR: The simulation results show that the proposed file delivery protocol could effectively reduce the total file delivery time by several orders of astronomical units and enhance link efficiency with noticeable increments, especially under conditions of high bit error rates (above 10-5).

TL;DR: In this paper, a deep space delay tolerant network (DTN) multiple hop transmission method is proposed, which comprises the following steps: step (a) an originating node divides a file to be transmitted into several bundle data units, step (b) each data slot in i parallel sessions is transmitted and retransmitted; step (c) real-time evaluation is carried out on memory resource occupancy of the current node i and successful delivery probability of the bundle data unit of the DTN; and step (d) if the probability of successful delivery is larger than 05, a node

TL;DR: An analytical framework based on two-dimension Markov chain is proposed to evaluate the behaviors of bundles delivery in DTN intermediate nodes and results indicate that Dividing the source files into bigger bundles for transmission causes a longer storage-occupancy time on intermediary nodes and the transmission success probability of a bundle is more dependent on a DTN bundle size than on a LTP segment size.

TL;DR: In this paper, a space network visual simulation method based on high level architecture (HLA) is presented, where the information interaction of each network node adopts an HLA/RTI (run-time infrastructure) distribution system structure and a simulation process, the MATLAB (matrix laboratory) number simulation and the data analysis are adopted as members of a number calculation union, a database is adopted and is connected with the members of data collection union, an STK/VO (satellite toolkit/visualization option) technique is used as the integral scene simulation for

TL;DR: In this article, the authors proposed a deep space file transfer method based on relay store-forward, used for transmitting a file to a receiving terminal from a transmitting terminal by virtue of a relay satellite.
