Warning data dissemination using vehicular networks is envisioned in Intelligent Transportation System applications. Due to extended connectivity of roadway vehicles and consequent extension of region of data propagation, data may be accessed in some geographical areas where it is neither relevant nor effectively beneficial. Moreover, propagating data to irrelevant regions increases communication...
We investigate connectivity in ad hoc network formed between vehicles that move in the same direction on a typical highway. We use the common model in vehicular traffic theory in which a fixed point on the highway sees cars passing it separated by times with exponentially distributed duration. We obtain the distribution of the distances between cars, which allows us to use techniques from queuing...
One of the most promising and critical application of vehicular ad hoc networks (VANETs) is improvement of the road traffic safety. Currently there is a growing belief that putting an 802.11-like radio into road vehicles could help the drivers to travel more safely. Although research in this field is in preliminary stage, some simple implementations are quite promising; to the best of our knowledge...
