Abstract
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 discovery. 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 broadcast storm
problem. The proposed architecture can effectively disseminate anddiscover 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.
