In conventional networks, routing problem can be modeled as the design of an efficient
source-to-destination route based on persistent end-to-end paths. However, in a delay …

In a delay tolerant network (DTN), nodes are connected intermittently and the future node
connections are mostly unknown. Since in these networks, a fully connected path from …

In a delay tolerant network (DTN), nodes are connected intermittently and the future node
connections are mostly not known. Therefore, effective forwarding based on limited …

Conventional routing algorithms rely on the existence of persistent end-to-end paths for the
delivery of a message to its destination via a predesigned path. However, in a delay tolerant …

Abstract Delay Tolerant Networks (DTNs), also called as intermittently connected mobile
networks, are wireless networks in which a fully connected path from source to destination is …

Abstract Delay Tolerant Networks (DTNs) provide message delivery services to users via
intermittently connected nodes. In DTNs, routing is one of the most challenging issues since …

In this paper, we address the problem of efficient routing in delay tolerant networks. We
propose a new routing protocol dubbed as ORION. In ORION, only a single copy of a data …

It is challenging to deliver messages in a network where no instant end-to-end path exists,
so called delay-tolerant network (DTN). Node encounters are used for message forwarding …

Delay tolerant networks (DTNs) make use of opportunistic encounters of nodes for
communication. The characteristics of high mobility of nodes, frequent link variation and long …

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 …
