SAT01-1: Study and Performance Analysis of ARQ-based and Transport Layer Coding Schemes over Deep Space Networks

The extension of telecommunication frontiers towards deep space scenarios has opened new horizons in the way of designing network infrastructures and has raised the necessity of developing novel communication paradigms, more suited to this specific environment. Under this view, the exploitation of TCP-based transmission schemes does not offer satisfactory results. On the contrary, the use of erasure coding schemes and more appropriate automatic repeat request (ARQ) schemes, available within the transport layer coding-based and the Consultative Committee for Space Data Systems (CCSDS) protocol architectures, respectively, assure better performance results. In this paper, the adoption of erasure codes within CCSDS protocol stack is considered and its effectiveness is evaluated with respect to ARQ-based transmission schemes available within the CCSDS file delivery Protocol.
