We propose a framework for efficiently disseminating large data items associated to locations where they are produced by vehicles and desired by drivers of different vehicles in a VANET. The framework consists of a scheme for aggregating drivers' demand for location dependent data using soft-state sketches, a scheme for understanding the condition of data(More)
This paper proposes an efficient scheme for sharing location dependent data such as pictures of traffic accidents and congestion for assisting car drivers using vehicular ad hoc networks. Assuming that drivers request location-dependent data when they face a scene indicating an accident or they are caught in congestion, multiple requests will be sent from(More)
In this paper, we described the design of Demand map-based data distribution scheme and preliminary simulation results. The soft-state sketch is used for the data structure of elements of Dmap information to make the size of Dmap on memory small and the system scalable. We are working on developing detailed design of the Dmap and Dmap-based data(More)
