Confirmed delivery multicast protocol in delay-tolerant and disruptive networks
Celandroni N., Ferro E., Gotta A.
This paper evaluates the performance of the NORM multicast transport protocol, when used in mobile satellite channels that behave as in delay-tolerant and disruptive networks (DTN). Comparisons are made between multicast transmissions with and without interleaver when NORM is used in "confirmed delivery" mode.Source: ISTI Technical reports, 2011

On the applicability of reliable transport protocols in satellite delay tolerant and disruptive networks
Celandroni N., Ferro E., Gotta A., Luglio M., Roseti C.
Delay tolerant networking (DTN) is an emerging technology introduced for deep-space communications to address both very large propagation delay or link disruptions. The DTN paradigm results promising in several satellitebased scenarios where either physical or service interruption might be experienced. This paper focuses on a set of selected satellite-based scenarios, where the DTN paradigm adoption greatly improves the unicast and multicast communications' performance with limited costs in terms of both software add-ons and architectural modifications.Source: ISTI Technical reports, 2011

SatNEx III - ESR "Executive summary report"
De Cola T., Bisio I., Davoli F., Cello M., Ferro E., Celandroni N., Gotta A., Cruikshank H., Caini C., Firrincieli R., Roseti C.
The aim of this document is to summarise the main results achieved in the study "Applicability of Delay and Disruption Tolerant Networks to Space Systems" being part of the CoO-1 call of SatNEx III project, commissioned by ESA in contract RFQ/3- 12859/09/NL/CLP. The investigation carried out here can be seen as an pre-Artes 1 study, possibly motivating the begin of new studies about the use of DTN in more focused scenarios. In particular, the aim of this analysis has been primarily on the current research activities performed in this field and then on the potential applications that the DTN architecture may have in some satellite-based scenariosSource: Project report, SatNex III, 2011

SatNEx III - FR "Final report"
De Cola T., Bisio I., Davoli F., Cello M., Ferro E., Celandroni N., Gotta A., Cruikshank H., Caini C., Firrincieli R., Roseti C.
The aim of FR (Final Report) is to exhaustively report the achievements and the main findings of Task 3 activity, by taking as reference what already reported in TNs 3.1, 3.2, 3.3, and 3.4. Being the aforementioned documents already focusing on some aspects of the overall activity, this document attempts to highlight the main points related to the application of DTN in satellite-based environments, in terms of suitable scenarios, emulation campaigns, and final recommendations. As not all aspects are dealt with the same detail in this report, the interested reader is kindly requested to refer the material available in the related deliverables.Source: Project report, SatNex III, 2011

The aim of this Technical Note (TN) is to provide an overview of the potential role of the satellite in future wireless sensor networks (WSN). TN includes a study of possible architectures for the interworking between WSNs and satellite, addressing the relevant issues in terms of both performance and security. The main achievement is the identification of three satellite-WSN meaningful scenarios, which will be the baseline for activities of Task 2.1Source: Project report, SatNex III, Deliverable TN 2.1, 2011

Performance analysis of systematic upper layer FEC codes and interleaving in land mobile satellite channels
Celandroni N., Gotta A.
This work provides an analytical method for evaluating the performance of upper layer forward error correction (FEC), when used together with interleaving on land mobile satellite channels, in terms of residual (after decoding) packet loss rate. In addition, simulations highlight the overheads introduced by this technique, which depend on the channel statistics, in terms of additional packet delivery delay, bandwidth consumption, and computation power required. We will show why the interleaver is mandatory in some environments, due to the severe disruptive characteristics of the channel, according to measurement campaigns promoted by the European Space Agency. This analysis provides the expression of the residual packet loss rate, when systematic FEC coding blocks are interleaved at packet level (i.e. when a cyclic redundancy check and a sequence number identify a precise data unit). This method can be employed for performance evaluation of recent and future mobile communication systems that take advantage of upper layer FEC and interleaving techniques.Source: IEEE transactions on vehicular technology 60 (2011): 1887–1894. doi:10.1109/TVT.2011.2122253

SatNEx III - recommendations for future R&D activities
Celandroni N. Ferro E., Gotta A., De Cola T., Caini C., Firrincieli R., Haitham C., Igor B., Marco C.
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 fieldSource: Project report, SatNex III, Deliverable TN 3.4, 2011

A survey of architectures and scenarios in satellite-based wireless sensor networks: System design aspects
Celandroni N., Ferro E., Oligeri G., Gotta A., Luglio M., Bisio I., Cello M., Davoli Franco, Panagopoulos, A. D., Poulakis, M., Vassaki S., De Cola Tomaso, Marchitti M. A., Hu Y. F., Verma S., Xu K., Acar G., Roseti C.
This paper is not a survey related to generic wireless sensor networks (WSNs), which have been largely treated by Akyildiz et al. in [1], and later in a number of survey papers addressing more focused issues; rather, it specifically addresses architectural aspects related to WSNs in some way connected with a satellite link, a topic that presents challenging interworking aspects. The main objective is to provide an overview of the potential role of a satellite segment in the future wireless sensor networks. In this perspective, requirements of the most meaningful WSN applications have been drawn and matched to characteristics of various satellite/space systems in order to identify suitable integrated configurations.Source: ISTI Technical reports, 2011

Panagopoulos A. D., Poulakis M., Vassaki S., Gotta A., Celandroni N., Ferro E., Bisio I., Davoli F., Cello M., Rosetti C., Luglio M., Marchitti M., Munari A., De Cola T.
The aim of this Technical Note (TN) is to present the issues and the general assumptions of the application scenarios that have been selected in the previous deliverable TN 2.1 "WSN-Satellite Network Architecture and Scenarios". The methodologies that will be studied are briefly described. In the first part, the general assumptions regarding the quality of service (QoS) in Wireless Sensor Networks (WSNs), the technologies and the traffic profiles are given. In the next part, the TN is devoted to presentation of the principles of collaborative beamforming and of the link budget parameters, while afterwards the techniques for clustering (MADM and game theory) and data fusion, and the cooperative routing for satellite-controlled WSNs are presented. Finally, the assumptions and the simulation setup for the efficient access and transport techniques among sensors and satellite are presented. In all the above-described scenarios the energy constraints are consideredSource: Project report, SatNEx III, Deliverable TN 2.2.1, 2011
