“…De Cola et al, in [14][15][16], propose an erasure coding-based CFDP extension for critical environments with intermittent links, deep fading, and hard shadowing in which the feasibility is validated in various channel conditions of different BERs and bandwidths. A loss-tolerant file delivery protocol with only one-way reliable transmission is proposed in [17], which can further reduce obvious overhead in CFDP. In [18], rateless coding, such as fountain codes, is incorporated into the CFDP implementation, which could make the packets interleaved before transmission to resist channel errors.…”

In this paper, we propose a novel relaying protocol based on the Consultative Committee for Space Data Systems File Delivery Protocol (CFDP) over a weather-dependent Ka-band channel, which exploits a dual-hop link instead of the traditional single-hop link for a 100% file delivery service on scientific data return. We designed the specific model of the proposed protocol and provide the analytical results on the expected latency and link efficiency of the file delivery. Based on the proposed model, we discuss the exact location of the relay node that could minimize the expected file delivery delay by examining several practical relay locations for the proposed protocol. The simulation results show that, compared with the traditional CFDP, 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 ).

“…Several interesting papers have reported improvements of CFDP performance in those challenge environments [9][10][11][12][13][14][15][16][17][18][19][20][21][22]. In [9][10][11], respectively, traditional CFDP over cislunar, GEO, and LEO links are theoretical analyzed and evaluated by extensive simulations.…”
