SatNEx III - recommendations for future R&D activities

This document is aimed at highlighting the possible future R&D lines for DTN application, based on the findings summarized in TNs 3.1, 3.2 and 3.3. In particular, the attention is devoted to the scenarios where the applicability of DTN would be beneficial, by replacing the current protocol and architecture solutions, which instead suffer from some performance degradations. Finally, the analysis of the DTN software features for each scenario is carried out as well in order to identify the gaps that can be still bridged and the functionalities that presently already help DTN overcome performance of other solutions or at least to mitigate scenario-induced impairments. Last points are finally dedicated to the standardization and dissemination activity resulted from this study, thus showing and motivating the research activity in this field
