Not Found ? – A Quest For DTN Applications

چکیده
1. EXTENDED ABSTRACT Delay-tolerant Networking (DTN) [3] has moved a long way from its—for many probably somewhat elite—origin of a technology for an Interplanetary Internet in the late 1990s to an established research discipline. One major contributor to this trend was the observation that quite a few terrestrial networks exhibit delay-tolerant properties, albeit of different nature: from sparse mobile ad-hoc to sensor networks to mobile Internet access, we find delay tolerance as an important element to describe communication behavior and to design protocols suitable for operation in the respective challenged networking environment. And even fixed infrastructure networks may benefit from delay-tolerant approaches to data transmission [7]—as did UUNet decades ago, when forwarding mails and news in a multi-hop store-and-forward fashion enabled communication involving machines that were not “always on” in the first place. Delay-tolerant networking has contributed to our understanding of networking at least in a twofold manner:

A survey of routing and data dissemination in Delay Tolerant Networks
Delay Tolerant Networks (DTNs) have practical applications in various fields. DTNs have been studied in-depth by many researchers and multiple high quality survey papers have been produced which analyzes DTN features, taxonomies, and applications. In recent years, interest in DTN research has rekindled as there are several emerging network-based application domains that require delay tolerance ...
متن کاملRouting Schemes for Delay-Tolerant Networks - An Applications Perspective
Delay Tolerant Networks (DTNs) represent a class of wireless networks that experience frequent and long lasting partitions due to sparse distribution of nodes in the topology. A traditional TCP/IP setting assumes the definite existence of a contemporaneous end-to-end path between any source-destination pair in the network. Any setting that violates this assumption may be considered as a potenti...
متن کاملModeling message diffusion in epidemical DTN
A Delay and Disruption-Tolerant Network (DTN) is a fault-tolerant network where end-toend connections are not required for message transmissions between nodes. Usually, a DTN is implemented as a wireless mobile ad hoc network that can be applied, for instance, to rapidly build a basic telecommunication infrastructure in case of catastrophes and disasters, or to support communication in a disrup...
متن کاملA novel congestion control framework for delay and disruption tolerant networks
Delay and Disruption Tolerant Networks (DTNs) are networks that experience frequent and long-lived connectivity disruptions. Unlike traditional networks, such as TCP/IP Internet, DTNs are often subject to high latency caused by very long propagation delays (e.g. interplanetary communication) and/or intermittent connectivity. Another feature that sets DTNs apart from conventional networks is tha...

Delay Tolerant Network (DTNs) is a wireless network that experiences frequent connectivity and due to mobility of nodes long duration partitions occurred during transmission of data. DTN has the main feature that there is not full path present from source to destination. In Delay Tolerant Network (DTN), traditional routing protocol for mobile Ad-hoc protocol to be ineffective to extend of messa...
