Towards opportunistic sensed data dissemination in vehicular environments

This paper proposes guidelines for the design of dissemination protocols for data sensed in vehicular environments in view of a number of potential applications. We organize the data dissemination process in three main tasks: discovery, assessment, and seizing of data exchange opportunities. One major problem is the limitation in bandwidth due to large amounts of data and short communication time slots. We elaborate on this problem by presenting preliminary results which favor an approach which disseminate date fairly over the nodes in the network.
