摘要：Due to recent developments in wireless communication networks, Vehicular Ad-hoc Networks (VANETs) technologies have received a lot of attention in the fields of information sharing and service discov- ery. However, due to the ever-shifting mobility of vehicle topology, vehicles moving along non-fixed routes may not find suitable next-hop vehicles. This paper proposes schemes to effectively circulate and discover service information with the aid of public transportation systems. Bus routes can be used to create a backbone structure on which data can be posted and circulated to avoid the broad- cast storm problem. The proposed architecture can effectively disseminate and discover the required data through the traffic infrastructure and mobile vehicles. Experimental results demonstrate that the proposed scheme outperforms other schemes in terms of packet delivery ratio and end-to-end delay. Moreover, the overhead of this scheme is less than other schemes with an increasing of number of service requests
