A DTN approach to satellite communications
IEEE Journal on Selected Areas in Communications, 2008Satellite communications pose serious challenges to transport layer performance, mainly because of long propagation delays (especially in geosynchronous systems) and the possi ble presence of random errors on the satellite link. Solutions that cope with these impairments usually rely upon either the adoption of enhanced versions of transport protocols,

DTN for LEO Satellite Communications
2011Satellite communications are an interesting and promising application field for Delay/Disruption Tolerant Networking (DTN). Although primarily conceived for deep space communications and sensor networks, it was immediately recognized that DTN was applicable to satellite environments, in particular to cope with the intermittent channels typical of LEO ...

Broadcasting in DTN as an epidemic dynamics
ACM SIGMOBILE Mobile Computing and Communications Review, 2010Broadcasting in DTNs is an important problem with various applications in disaster relief, rural networks, vehicular networks. Significant work has been done in epidemiology that have addressed similar problems in a different setting. A natural question is to understand the applicability of these well understood theories in DTNs.

Wireless Mobile Ad-hoc Networks (MANETs) are characterized by frequent and unpredictable disconnections, due to mobility, interference, power management or any other issues. Such disconnections result in the failure of MANET routing protocols that are designed to establish end-to-end paths between the communicating nodes.This work focuses on enhancing ...

SCinet DTN-as-a-Service Framework
2019 IEEE/ACM Innovating the Network for Data-Intensive Science (INDIS), 2019Transferring big data over Wide Area Networks (WANs) is challenging because optimization is dependent on the specifics of multiple parameters. Network services, paths, and technologies have different characteristics, including loss rate, latency, and available capacity.

Multi-copy replication is an efficient approach for routing a message between a pair of source and destination nodes in a Delay Tolerant Network (DTN). However, such an approach disseminates an undesirable number of replicas of messages, which increases the overhead of the network.

Performance evaluation of NSC in DTNs
2015 49th Annual Conference on Information Sciences and Systems (CISS), 2015Network coding has been proposed as a promising solution to improve the message delivery ratio and delivery delay in disruption tolerant networks. However, it suffers from a significant waste of limited contact times due to exchanges of redundant encodings when nodes carry similar sets of encodings. In order to reduce these wasteful exchanges, recently

We describe DTN trials carried out as part of the N4C project over the last year. These trials took place in two locations, Padjelanta national park in northern Sweden between early July and late August 2010 and Galway, on the west coast of Ireland, during early 2011.

On the Spatial-temporal Reachability of DTNs
2013As traditional “Connectivity” concept from the Internet ignores the possibility of opportunistic contacts in DTNs, this paper brings time dimension into consideration, proposes Spatial-Temporal Path, Spatial-Temporal Reachability and K-Reachability in order to better describe the whole communication process and “Eventual Transportability” of DTN ...
