In conventional networks, such as the Internet, it is assumed that there exists a fully
connected path between any pair of nodes at any time. In delay tolerant networks (DTN) …

Delay tolerant networks (DTNs) are wireless mobile networks that do not guarantee the
existence of a path between a source and a destination at any time. When two nodes move …

This paper addresses the problem of routing in delay tolerant networks (DTNs). Normally,
one of the most fundamental requirements in delay tolerant networks is to find a …

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

A Delay Tolerant Networks is a network where contemporaneous connectivity among all
nodes does not exist. Conventional routing protocols are not suitable for DTN because they …

In a Delay Tolerant Network (DTN), the Probabilistic Routing Protocol using the History of
Encounters and Transitivity (PRoPHET) routing protocol mainly uses the delivery …

Delay Tolerant Networks (DTNs) are a class of emerging networks that experience frequent
and longduration partitions. Compared with the conventional networks, the distinguished …

Delay Tolerant Networks (DTNs) differ from the traditional Mobile Ad Hoc networks
(MANETs) in that DTNs are not always interconnected. The issue of routing data in a DTN is …

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 …

In this paper, we propose a novel contact-based hybrid routing scheme for delay tolerant
networks (DTNs). The scheme combines utility and centrality metrics to make forwarding …
