In opportunistic environments data forwarding is challenging where connectivity is
intermittent because of network partitioning, dynamic topologies and long delays. Traditional …

In a Delay Tolerant Network (DTN), nodes are intermittently connected. In order to deliver a
message from a source node to a destination node, the message is copied and forwarded to …

Due to the uncertainty of transmission opportunities between mobile nodes, delay tolerant
networks (DTN) routing exploits the opportunistic forwarding mechanism. This mechanism …

Without the assumption of contemporaneous end to end connectivity in challenged wireless
networks, Delay Tolerant Networking (DTN) routing is an important research area. The …

Delay Tolerant Network (DTN) has been emerged to support the network connectivity of the
disruptive networks. A variety of routing methods have been proposed to reduce the latency …

Node mobility and end-to-end disconnections in Delay Tolerant Networks (DTNs) greatly
weaken the effectiveness of data transmission. Although social-based strategies can be …

This paper presents a multicast Delay Tolerant Network (DTN) routing protocol with the goal
of maximizing an economic gain for Device-to-Device (D2D) commercial content …

In this paper, we enhanced the Binary Spray and Wait (BS &W) routing protocol and create
two versions of Spray and Wait (S&W-V1 and S&W-V2) and evaluate and compare their …

Due to the unstable network topology of Delay Tolerant Networks (DTNs), multi-copy routing
is often used to increase the reliability of message delivery. However, this routing approach …
