Abstract

Vehicular Ad Hoc Networks (VANETs) is an emerging type of information networks in urban areas. A lot of research has been done in the area of increasing the vehicle awareness by disseminating collision and congestion warnings, and parking place availability information. In this paper we propose a novel idea and framework for dissemination of location based information, called digital maps, which are useful not only directly for the drivers and vehicle onboard navigation systems, but also external entities, such as tourists, environmental scientists, emergency services, advertisement companies. Centralized authority defines cooperative knowledge collection tasks and disseminates orders in the network while every vehicle decides which tasks it takes part of, based on hardware equipment, geographical position and individual interests of the driver. The results of preliminary simulation, with vehicles driving in an artificial city, show, that 200 vehicles/km 2 is minimum reasonable density to deploy proposed dissemination system.
