An Efficient Crowdsourcing Search Scheme in Vehicular Ad hoc Networks

In recent years, Vehicular Ad-hoc Networks (VANETs) have become a popular research field. In addition, conditions happened surrounding our life often have the demand to be supported by other people, and these conditions often occur on the road. This study proposes an efficient crowdsourcing search scheme in VANETs to search objects and collect data. Our proposed mechanism is based on the virtual backbone construction in VANETs. The regional data exchange can be limited, and the packet transmissions can be reduced. We have established coordinator and header mechanisms to manage the information of region nodes, reduce the amount of packet transmission and improve searching efficiency. Experimental results show that our schemes can effectively provide assistance in terms of search efficiency and satisfactory ratio.
