ABSTRACT: In vehicular ad-hoc
networks (VANETs), store-carry-forward approach may be used for data sharing,
where moving vehicles carry and exchange data when they go by each other. In
this approach, storage resource in a vehicle is generally limited. Therefore,
attributes of data that have to be stored in vehicles are an important factor
in order to efficiently distribute desired data. In VANETs, there are different
types of data which depend on the time and location. Such kind of data cannot
be deployed adequately to the requesting vehicles only by popularity-based
rule. In this paper, we propose a data distribution method that takes into
account the effective life and area in addition to popularity of data. Our
extensive simulation results demonstrate drastic improvements on acquisition
performance of the time and area specific data.
