To cope with explosive traffic demands on current cellular networks of limited capacity,
Disruption Tolerant Networking (DTN) is used to offload traffic from cellular networks to high …

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

Mobile ad-hoc networks (MANETs) assume that mobile nodes voluntary cooperate in order
to work properly. This cooperation is a cost-intensive activity and some nodes can refuse to …

Due to the pervasiveness of mobile devices, a vast amount of geolocated data is generated,
which allows us to gain deep insight into human behavior. Among other data sources, the …

In this paper, we advocate Crowdlet, a novel self-organized mobile crowdsourcing
paradigm, in which a mobile task requester can proactively exploit a massive crowd of …

In wireless underground sensor networks (WUSNs), due to the dynamic underground
channel characteristics and the heterogeneous network architecture, the connectivity …

Foundational work in the area of opportunistic networks has shown that the distribution of
intercontact times between pairs of nodes has a key impact on the network properties, for …

Mobile crowdsensing systems aim at providing various novel sensing applications by
recruiting pervasive users with mobile devices, which are now equipped with enriched built …

Offloading traffic through opportunistic communications has been recently proposed as a
way to relieve the current overload of cellular networks. Opportunistic communication can …

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 …
