Congestion in DTNs happens when the forwarding path to destination does not exist and a
node runs out of buffer space. Several works have shown that the situation is hard to …

The routing efficiency in Delay Tolerant Networks (DTN) with social characteristics degrades
owing to intermittent connection and high latency. Additionally, congestion is another issue …

Delay tolerant networks (DTN) are kind of sparse networks in which end-to-end connectivity
between source and destination is not always guaranteed. The Internet is the basic source …

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 …

In delay tolerant networks, most of the existing message forwarding algorithms prefer to
deliver messages to the nodes with a higher popularity or centrality in the hope of …

Delay Tolerant Networks (DTNs) are sparse mobile ad-hoc networks in which there is
typically no complete path between the source and destination. Although many routing …

In order to achieve data delivery in Delay Tolerant Networks (DTN), researchers have
proposed the use of store-carry-and-forward protocols: a node there may store a message in …

In Delay Tolerant Networks (DTNs) with resource constraints such as short contact durations
and small buffers, message scheduling and drop prioritization is a critical issue as it affects …

Delay‐tolerant networks are sparse mobile ad hoc networks in which there is typically no
complete path between the source and destination. Although many routing schemes for …
