Abstract A Delay Tolerant Network (DTN) is a network capable of handling long delays and
data loss efficiently in various challenged scenarios and environments. Owing to the …

Delay-tolerant networks (DTNs) consist of nodes moving around and occasionally coming
into each other's proximity. During the limited proximity time, nodes can exchange data; this …

Ensuring the security and privacy of vehicular ad hoc networks (VANETs) and related
services such as secure payment has been the focus of recent research efforts. Existing …

Opportunistic Networks (OppNets) enable communication in highly stressed environments
with intermittent connectivity and are categorized by long and variable delays as well as …

Network congestion is a well-known problem that may heavily affect the overall network
performance. Congestion control approaches in Intermittently-Connected Networks (ICNs) …

In order to understand the message propagation performance in Mobile ad-hoc Networks
(MANETs), various methods and models have been proposed in the literature by applying a …

This work proposes an analytical model based on absorbing semi-Markov process for
predicting the expected pairwise delivery delay for single and multi-copy opportunistic …

Cellular network data traffic can be offload onto opportunistic networks. This paper proposes
a Distance-based Opportunistic Publish/Subscribe (DOPS) content dissemination model …

The opportunistic networks have shown to be an interesting communication infrastructure for
supporting mobile collaborative systems in several application scenarios like disaster relief …

This paper proposes an analytical model that captures the expected pairwise delivery delay
in an opportunistic network when the source can generate multiple copies of the message …
