A New Paradigm for Querying Blobs in Vehicular Networks
Ouri Wolfson, Bo Xu · IEEE Multimedia · 2013
In this article, the authors study querying binary large objects (blobs) such as video and voice clips in a network of vehicles communicating wirelessly. They introduce a novel paradigm, describe a set of derived query-processing strategies and compare them along three dimensions: push versus pull, whether or not a communication infrastructure is utilized, and whether metadata dissemination is separated from blob dissemination. They analyze these strategies theoretically and experimentally in terms of answer throughput and communication overhead.
