Realistic mobility models are crucial for the simulation of Delay Tolerant and Opportunistic
Networks. The long standing benchmark of reproducing realistic pairwise statistics (eg …

Opportunistic or delay-tolerant networks (DTNs) may be used to enable communication in
case of failure or lack of infrastructure (disaster, censorship, remote areas) and to …

K-shell (or k-core) graph decomposition methods were introduced as a tool for studying the
structure of large graphs. K-shell decomposition methods have been recently proposed as a …

Opportunistic or Delay Tolerant Networks (DTNs) may be used to enable communication in
case of failure or lack of infrastructure (disaster, censorship, remote areas) and to …

Opportunistic Networking allows wireless nodes to exchange data and information of
interest with peers in communication range. These nodes form a large, dynamic, multi-hop …

Social Network Analysis (SNA) has emerged as a promising method for designing data
dissemination algorithms over Delay Tolerant Networks (DTN). These algorithms try to …

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 …

To provide communication services in delay-tolerant networks (DTNs) where there may exist
no end-to-end paths between mobile node pairs, a variety of relaying and routing algorithms …

Opportunistic networks are formed by people carrying mobile devices with wireless
capabilities. When in mutual transmission range, the nodes of such networks use device-to …

In Delay Tolerant Networks (DTN), contemporaneous end-to-end paths are rarely available.
Routing in such networks is therefore one of the challenging issues. When the DTN is made …
