Delay-tolerant Networking (DTN) enables communication in sparse mobile ad-hoc networks
and other challenged environments where traditional networking fails and new routing and …

3G networks are currently overloaded, due to the increasing popularity of various
applications for smartphones. Offloading mobile data traffic through opportunistic …

Abstract movement models, such as Random Waypoint, do not capture reliably the
properties of movement in the real life scenarios. We present and analyse a movement …

Personal mobile devices are increasingly equipped with the capability to sense the physical
world (through cameras, microphones, and accelerometers, for example) and the, network …

Communication networks, whether they are wired or wireless, have traditionally been
assumed to be connected at least most of the time. However, emerging applications such as …

Delay-tolerant Networking (DTN) enables communication in sparse mobile ad-hoc networks
and other challenged environments where traditional networking fails and new routing and …

With emerging demands for local area services, device-to-device (D2D) communication is
conceived as a vital component for the next-generation cellular networks to improve spectral …

Mobile devices are increasingly equipped with multiple network interfaces with
complementary characteristics. In particular, the Wi-Fi interface has high throughput and …

This paper presents ORWAR, a resource-efficient protocol for opportunistic routing in delay-
tolerant networks. Our approach exploits the context of mobile nodes (speed, direction of …

To cope with increasing vehicular traffic and extensive application demands on vehicular
cellular networks, opportunistic vehicular networks are used to disseminate mobile data by …
