Abstract: The problem of information inquiry in vehicular networks is investigated. An efficient information inquiry scheme is proposed. First, query routing and reply routing are designed, respectively. Then, a strategy of packet forwarding is designed. Finally, abnormal situation handling and optimization are discussed. Real trace driven simulation experiments are conducted. Performance results demonstrate that, compared with an alternative solution, the proposed scheme can achieve lower latency and higher delivery ratio.

Key words: vehicular networks, information inquiry, routing, optimization
