FREAK DTN: Frequency Routing, Encounters And Keenness for DTN
2014 IFIP Wireless Days (WD), 2014Mobile systems monitoring is an application area for Mobile Wireless Sensor Networks (MWSN), which introduces some specific challenges. Delay/Disruption architecture tackles some of these issues, such as delay and connectivity disruptions, and thus has already been used in this context. However, WSN nodes have severe limitations, concerning storage and

Proceedings of the 2008 ACM CoNEXT Conference on - CONEXT '08, 2008
Delay-tolerant network architectures exploit mobile devices carried by users to enable new networked applications. Efficiently routing information through these DTNs faces new challenges such as mobility and the dynamic nature of the network. Previous work has looked at using encountered nodes to build a social network for routing.

On the Effects of Cooperation in DTNs
2007 2nd International Conference on Communication Systems Software and Middleware, 2007In a delay tolerant network (DTN) the nodes may behave autonomously deciding on their own whether to implement or not the rules of a routing algorithm. In this paper, the effects of node cooperation (or lack of it) are explored for three well-known routing algorithms proposed for DTNs with respect to the message delivery delay and the transmission ...

2009 International Conference on Ultra Modern Telecommunications & Workshops, 2009
As the space communications infrastructure of the near future is yet to be standardized, many protocols have been proposed to cope with issues such as long propagation delays, high packet error rates and intermittent connectivity. In that context, we have designed a testbed, which incorporates Space conditions, mission scenarios and Space communication

On the utility of overhearing in DTN
2014 IEEE Ninth International Conference on Intelligent Sensors, Sensor Networks and Information Processing (ISSNIP), 2014Limited contact bandwidth is one of the main resource constraints in delay/disruption tolerant network (DTN). In this paper, we investigate the use of overhearing to relieve the bandwidth constraint. We ask two questions in this work. First, how many receivers are within the transmission range when a sender transmits?

Performance Comparison of DTN Routing Protocols in Vehicular-DTN Environment
2014 Ninth International Conference on Broadband and Wireless Computing, Communication and Applications, 2014The Delay/Disruption Tolerant Networking (DTN) aims to provide inter-operable communications with wide range of networks which have poor performance characteristics. In this paper, we propose a message suppression method for Vehicular DTN (VDTN).

Packet size and DTN transport service: Evaluation on a DTN Testbed
International Congress on Ultra Modern Telecommunications and Control Systems, 2010We present a study of DTN transport layer service, evaluating its performance during a file transmission from a Mars relay satellite towards Earth. The experiments are being held in a DTN Testbed designed and implemented for emulating and evaluating deep-space communications. Bundle Protocol truncates application data into bundles of different size and

DTN-tg A DTN Traffic Generator
2012Delay-Torelart Networking becomes a rapidly developing network technology in the area of Challenged Networks. Research community has made significant progress towards developing a set of protocols that enhance the reliability and efficiency of DTNs. Despite the broad acceptance of DTN architecture, there is not yet any reliable testing tool that could ...

DTN-RSim: An event-based routing simulator for DTN
International Conference on Computer Networks and Information Technology, 2011Traditional routing protocols work only in the presence of end-to-end connectivity. They fail to route messages in a highly dynamic and disrupted network. From the beginning of last decade, delay-tolerant routing protocols have been developed and deployed for challenged areas and applications.

Virtualization Technologies for DTN Testbeds
2010At present, Internet is based on the availability of a continuous path from the source to the sink node and on limited delays. These assumptions do not hold in “challenged networks”, which comprise a wide variety of different environments, from sensor networks to space communications (including satellite systems).
