    ABSTRACT: 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. We also give an overview of the updates made to the hardware and software components used since previous trials and we outline an upcoming DTN trial planned for summer 2011 as part of the SAIL project.

    ABSTRACT: Delay- and disruption-tolerant networking (DTN) is an emerging area of networking research that will benefit from real-world trials and testbeds. We describe a week long DTN trial carried out during the summer of 2009 in the Laponia area of Northern Sweden that involved the provision of basic email and web services to users who were 57km distant from any power or networking infrastructure. The trial validated our design and successfully demonstrated the use of email via helicopter-transported data-mules. With the aim of making it easier for others to replicate this kind of trial, the hardware and software used are described with references to full specifications, as are the results of the initial 2009 trial. We also describe plans for an extended trial in summer 2010 in the same area. KeywordsDelay tolerant networking–DTN–DTN testbed

    ABSTRACT: Delay-Tolerant Networking (DTN) focuses on networking in challenged environments. As part of the Networking for Communications Challenged Communities (N4C) project (funded by the EU under the FP7 programme), TCD and Intel, together with help from other N4C partners constructed and operated a trial DTN in the Padjelanta national park in northern Sweden in July and August 2010. This report describes the email and web applications provided over DTN during the trial.

    ABSTRACT: Delay- and disruption-tolerant networking (DTN) grew out of attempts to develop an interplanetary Internet but has evolved into an active area of networking research, with applications in space networking, military tactical networking, and networking for various challenged communities. The DTN Research Group provides an open forum in which DTN researchers and developers can collaborate to further develop this experimental technology.

    ABSTRACT: We describe the design for a Delay Tolerant Network (DTN) node to be used in the N4C project's summer 2009 trials to be held in conjunction with the ExtremeCom workshop. The design uses COTS products and applications; the DTN2 implementation of the Bundle Protocol (BP) and provides basic network access, e-mail and web access via the DTN.

    ABSTRACT: At ExtremeCom 2009, we described and demonstrated a DTN router design that was used to provide web and mail services from the remote location (Staloluokta) during the workshop. In this short paper we give a brief overview of the results of that experiment and outline our plans for the N4C summer 2010 trials in Laponia, and for providing web and mail services to ExtremeCom 2010.
