The aim of this paper is to find the best strategies to carry and forward packets within VANETs that follows a Delay Tolerant Network. In this environment nodes are affected by intermittent connectivity and topology constantly changes.

Abstract
The aim of this paper is to find the best strategies to carry and forward packets within VANETs that follows a Delay Tolerant Network. In this environment nodes are affected by intermittent connectivity and topology constantly changes. When no route is available and the link failure percentage is high, the data must be physically transported by vehicles to destination. Results show how, using vehicles cooperation and several carry and forward mechanisms with different deliver priorities, is possible to improve performance for free in terms of data delivery.
