1 INTRODUCTION
In recent years, the explosive growth of the vehicle and the ubiquity of information needs combining communication network and vehicles. VANET in addition to the application of intelligent transportation aspect, it as a terminal to access the Internet, for car users to download data to meet the demand of its communication (Network on Wheels 2006, Internet ITS Consortium 2006). Drive through the Internet refers to being in the process of moving through the side of the road vehicular node of the wireless Access Point (Access Point, AP) connected to the Internet, download the required data and share advice another VANET application scenario. Vehicles in the process of moving between application of VANET technology can realize the vehicle and the communication between vehicles and roadside Internet access points. At present, the widely used onboard wi-fi broadband wireless access technology, for studying the Drive - thru Internet data transmission. The main reason is the use of 3 g, 4 g network is costly, relative to the high cost of its communication performance is not ideal (J.Ott, D. Kutscher. 2004). So on-board nodes by road network in the deployment of the Internet access point connected to the Internet, in order to satisfy the demands of the Drive - thru the Internet. Despite a massive deployment of VANET WLANs can give an area to provide high quality data service, But due to the number of AP required too much with very high cost, it is not feasible in practice (Z. Zheng, Z. Lu, S. Prasun, K. Santosh. 2010). In order to solve the problem of the high cost of the current AP deployment, literature adds a combination in VANET in Mesh and WIFI communication technology of the
auxiliary infrastructure to improve network performance, extend the coverage of VANET (B. Nilanjan, C. Mark, T. Don, L. Brian 2008).
