Delay tolerant networks (DTNs) are network environments with high latency, low data rate,
intermittent connection, and limited resources. The communication between the nodes is …

A key issue in delay tolerant networks (DTN) is to find the right node to store and relay
messages. We consider messages annotated with the unique keywords describing the …

In the recent years, the Delay Tolerant Networks (DTNs) have been increasingly researched,
offering alternative solutions in real-life contexts where the Internet cannot be used. Even if …

Routing protocols in delay tolerant networks usually utilize multiple message copies to
guarantee the message delivery, in order to overcome unpredictable node mobility and …

Delay tolerant networks are characterized by the sporadic connectivity between their nodes
and therefore the lack of stable end-to-end paths from source to destination. Since the future …

Delay Tolerant Network is an emerging research field. In this network, a long period of
network partition happens frequently. In this paper, we present the notion of QoN (Quality of …

In this article we will discuss the problem of routing in delay tolerant networks (DTNs). The
major problem in DTN networks is to find an end-to-end communication path between a …

Delay Tolerant Network (DTN) is a class of network architectures that address the lack of
continuous network connectivity. This issue has been studied for over a decade by …

Abstract Now-a-Days, researchers' engagement in the research works in the fields of
networking and telecommunication sector could be seen increasing day by day. Many of …

Recently Delay Tolerant Networks (DTNs) have been a successful paradigm especially for
the network environments where the nodes are characterized by opportunistic connectivity …
