在本文中，我们研究在混合车辆网络中查询多媒体数据，例如视频和语音片段，该网络由能够进行无基础设施短程通信和基础设施通信的车辆组成。我们引入了一组查询处理策略，这些策略在推与拉、是否利用基础设施通信以及元数据传播是否与多媒体传播分开方面彼此不同。我们从理论上和模拟上分析这些策略，并找出优于其他策略的策略。
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.
