Delay-tolerant Networking protocols render a huge variety of novel communication scenarios possible. One of them is the so called Ring Road approach, a world-wide message-ferry network built upon Low-Earth Orbit (LEO) satellites used to transfer data between different ground stations. By this approach a world-wide communication network may be deployed at very low cost which allows for ad-hoc integration...
The features of information dissemination in vehicular networks make it necessary to introduce Information-Centric Networking (ICN) technique to vehicular networks. However, some design principles of ICN must be implemented and extended in order to realize efficient data dissemination in vehicular networks. This paper proposes an approach for realizing ICN-based data dissemination in vehicular networks...
With the advancement of the urbanization process, traditional centralized dynamic route guidance systems become incapable of handling fast growing traffic large data, due to the computational complexity. In another aspect, the realtime vehicle routing services from customers, such as information pushing and travel time forecasting, are more demanding. Aimed at easing the traffic congestion pressure...
The delivery of IP packets to a set of elements lying within a designated geographical area, also known as geocasting, is an important aspect in vehicular networks. Geocast messages can be used, for instance, to warn drivers about road conditions (e.g., weather hazards) and therefore prevent accidents. In order for geocasting to work on the Internet, IP addresses must be associated with geographical...
In the Internet of the future, a flexible, dynamic combination of wireless and wired access networks is expected to be a key driver for enlarging the broadband communication service area. However, in general, the number of broadband wireless access points is limited due to their cost, and hence, they cannot cover the whole network. On the other hand, various message delivery schemes based on store-carry-forward...
Vehicular networks (VANET) attract a lot of attention in the research world. Novel vehicular applications need suitable communication mechanisms to extend in-vehicle capabilities and, be aware about surrounding events. However, these networks present some characteristics, such as high mobility or specific topologies. These properties affect the performances of applications and more effort should be...
The effectiveness of Intelligent Transportation Systems (ITS) depends on their ability to collect contextual data from various sources and appropriately generate and transport comprehensible, reliable and timely content to users. In such applications, the exchanged content is structured in space and time. Peer-to-peer(P2P) networks are the natural choice these applications due to their fault-tolerance,...
Structured, spatial-temporal data arises in many applications areas such as transportation, sensor networks or mobile services. Peer to peer networks are the natural choice for the distributed architecture required by these applications. However, a closer analysis of the available distributed hash table (DHT) based approaches shows their inefficiency since the data structure gets lost and the short...
