Multimedia data in hybrid vehicular networks
Bo Xu, Ouri Wolfson, Jie Lin · 2010
In this paper we study querying multimedia data such as video and voice clips in hybrid vehicular networks that consist of vehicles that are capable of both infrastructure-less short-range communication and infrastructure communication. We introduce a set of query processing strategies which differ from each other in terms of push versus pull, whether or not infrastructure communication is utilized, and whether metadata dissemination is separated from multimedia dissemination. We analyze these strategies theoretically and by simulations, and identify the one that is superior to the others.
