Vehicular delay-tolerant networks (VDTN) assumes the use of the delay-tolerant network (DTN) concept for vehicular communications in order to cope several issues, such as highly dynamic network topology, short contact durations, disruption, intermittent connectivity, variable node density, and frequent network fragmentation. These challenging characteristics of vehicular networks affect the design...
This paper analyses the performance of a new routing protocol for vehicular delay-tolerant networks, called GeoSpray. This geographic routing protocol performs a store-carry-and-forward, combining replication and forwarding/ routing decisions based on location information, with explicit delivery acknowledgments to improve network resources utilization. The performance of the proposed routing protocol...
Vehicular Delay-Tolerant Networks (VDTNs) use vehicles to carry data between network nodes, enabling network connectivity in sparse or partitioned opportunistic networks, where the node density is not high enough to establish end-to-end links. By implementing a store-carry-and-forward paradigm, VDTNs allow delay-tolerant data traffic from a variety of vehicular applications to be routed over time,...
Vehicular Delay-Tolerant Networks (VDTNs) aim to provide non-real time services and applications, such as electronic mail or file transfer, in environments with sparse and intermittent connectivity, variable delays, or where an end-to-end connection may not exist. Gathering contributions from opportunistic and cooperative networks, VDTN tries to generalize the delay-tolerant networks concept and apply...
Vehicular delay tolerant networks (VDTNs) were proposed as a novel disruptive network concept based on the delay tolerant networking (DTN) paradigm. VDTN network architecture uses vehicles to relay messages, enabling network connectivity in challenged scenarios. Due to intermittent connectivity, network nodes carry messages in their buffers, relaying them only when a proper contact opportunity occurs...
Developing an adequate network architecture for supporting data communications in vehicular networks is critical to overcome the challenges caused by highly dynamic network topology, connectivity disruption, and intermittent connectivity issues. Among several approaches available in the related literature to address these problems, vehicular delay-tolerant networks (VDTNs) appear as a recent and innovative...
