“…Once it was recognized that the space challenges were actually common to other "challenged networks", the research was enlarged to include all of these [2]. Although no more exclusive, space communications (including satellite [3], [4]) are still one of the most interesting applications of the DTN concept [5], [6], [7].…”

Although Delay-/DisruptionTolerant Networking, which originated from research on an Interplanetary Internet, has enlarged its scope to encompass all challenged networks, space applications are still one of its most important application fields. This paper deals with DTN communication from Moon to Earth, based on the use of a lunar satellite acting as a "data-mule" to collect data from a Lander located on the far side of the Moon. To make the scenario more interesting and complex from the point of view of possible security threats, we assume that data must be transferred to a non-institutional user connected to the Space Agency Control Centre via Internet. In particular, the paper investigates the state-of-the-art ability of ION, the NASA implementation of the DTN Bundle Protocol (BP), to cope with the many challenges of the space scenario under investigation, such as intermittent links, low bandwidth, relatively high delays, network partitioning, DTN routing, interoperability between LTP and TCP BP Convergence layers and security threats. To this end, the first part of the paper contains three brief overviews of the DTN architecture, the Bundle Security Protocol and the ION implementation. These facilitate comprehension of the following sections, dedicated to a detailed description of the experiment scenario and, most essentially, to the in depth discussion of the numerical results obtained with the latest ION version (3.0).

SUMMARY Delay‐Tolerant/Disruption‐Tolerant Networking (DTN) architecture will be used in future deep space missions, to enable autonomous networking operations and disruption‐tolerant data communications. Therefore, it is worth analyzing the performance of the DTN Bundle Protocol (BP) in a realistic deep space environment, reproducing the characteristics of Mars missions. After a comprehensive introduction on data communications between Mars and Earth, the paper presents the essential features of both the BP DTN architecture and the Licklider Transmission Protocol (LTP), adopted here as BP convergence layer on deep space links, thanks to its ability to cope with the very long delays typical of this environment. The focus of our experiments is on analysis of the bundle flow from a Mars lander to an Earth control center through an intermediate relay node, for which two configurations are considered, inspired to Odyssey and Mars Reconnaissance Orbiter missions, respectively. Results are obtained by means of a test bed consisting of some GNU/Linux personal computers running either Interplanetary Overlay Network (ION) or DTN2 BP implementations. The analysis of results aims to highlight the role played by BP and LTP in tackling the challenges of Mars to Earth communications. Copyright © 2013 John Wiley & Sons, Ltd.

“…Once it was realised that these challenges, and in particular intermittent links and network partitioning, were actually common to other "challenged networks", the research activity was enlarged to include all of these [2] and provide a common solution, instead of a multiplicity of particular solutions. Although no longer the only field, space communications (including satellite [3][4]) are still the most important application of the DTN concept [5][6][7] and the primary motivation for research.…”

Delay/Disruption-Tolerant Networking (DTN) originated from research on Interplanetary Internet and still today space applications are the most important application field and research stimulus. This paper investigates DTN communications between the Earth and the far side of the Moon, by means of a lunar orbiter acting as relay. After an introductory part, the paper presents a comprehensive analysis of the DTN performance that can be achieved on the identified communication scenario. The focus is on the evaluation of the stateof-the-art ability of Interplanetary Overlay Network (ION), the NASA DTN implementation of Bundle Protocol (BP) and Contact Graph Routing (CGR), to meet the many challenges of the space communication scenario investigated (and more generally of a future interplaynetary Internet): intermittent links, network partitioning, scarce bandwidth, long delays, dynamic routing, handling of high priority and emergency traffic, interoperability issues. A study of security threats and Bundle Security Protocol (BSP) countermeasures complete the work. The many results provided, confirm the essential role of DTN in future space communications.
