Atmospheric ducting has a significant impact on electromagnetic wave propagation. Radio
signals that are trapped and guided by the atmospheric duct can travel a much longer …

Delay and disruption tolerant networks (DTNs) may experience frequent and long-lived
connectivity disruptions. Unlike traditional networks, such as the TCP/IP-based Internet …

The number of online devices with on board sensors is growing steadily in the last years,
leading to many solutions depending on data crowd-sourcing. In these scenarios, usually …

Abstract Delay Tolerant Networks (DTNs) often suffer from intermittent disruption due to
factors such as mobility and energy. Though lots of routing algorithms in DTNs have been …

Challenged networks represent a very special class of networks characterized by widely
varying network conditions such as intermittent connectivity, a heterogeneous mix of …

The delay tolerant networks (DTN), which form the mobile and wireless ad hoc networks, are
characterized by intermittent connectivity, asymmetric flow, high error rate and long or …

Due to the increasing dependence on network services of our society, research has recently
been concentrating on enhancing traditional protection strategies to withstand large-scale …

Abstract Delay and Disruption Tolerant Networks (DTNs) are networks that experience
