Internet connectivity is nowadays an ubiquitous service. However, on the road we obtain access using costly and limited data cellular network subscriptions. This, along with significant network congestion, severely limits network use. Opportunistic access to indoor APs is limited by three factors. First, establishing a link to an AP requires a significant amount of time, and, second, links on the street usually have poor quality. Third, the lifetime of this link is very short in a moving car, due to indoor APs generally covering small areas of the street. Combined, these factors thwart opportunistic use of APs for Internet access. In this paper, we propose a novel approach that leverages the large number of parked cars to separate these three factors and tackle them independently: a parked car can connect to an AP with a link that, despite its poor quality, has a long lifetime. A moving vehicle can instead benefit from the better link with a parked car and use it as a relay. As our experiments show, our approach enables the use of this free, high throughput channel for a number of non time-sensitive applications, thus reducing cost and the load on the cellular network.

. Abstract-Vehicles in a highway are connected to form a vehicular adhoc networks. (VANET) A VANET turns every participating vehicle into a wireless router or node. 100 to 300 meter distance is allowed between vehicles to cover a wide network range. In VANET network topology is rapidly changed due to high mobility of nodes. VANET uses infrastructure support to handle time sensitive data exchange process. Single-hop and multi-hop methods are used for VANET communication. Vehicle to Vehicle (V2V) communication and Vehicle to Infrastructure (V2I) communication methods are used for VANET data transmission. Mobile internet is provided with the consideration of signal range and mobility of vehicle.Internet access in vehicles is achieved with the support of VANET communication models. Downloading optimization scheme is used to improve the content downloading throughput. Roadside infrastructure, vehicleto-vehicle relaying, and penetration rate for communication factors are used in the system. Dynamic Network Topology Graph (DNTG) is constructed and sampling technique is applied to handle the data delivery process.Traffic pattern based scheduling scheme is used to improve the content delivery process. Data request level based bandwidth scheduling is used in the system. Infrastructure estimation is performed with historical data patterns. Data replication scheme is used to reduce the data delivery delay.

Abstract—We consider a system where users aboard communication-enabled vehicles are interested in downloading different contents from Internet-based servers. This scenario captures many of the infotainment services that vehicular com-munication is envisioned to enable, including news reporting, navigation maps and software updating, or multimedia file downloading. In this paper, we outline the performance limits of such a vehicular content downloading system by modelling the downloading process as an optimization problem, and maxi-mizing the overall system throughput. Our approach allows us to investigate the impact of different factors, such as the roadside infrastructure deployment, the vehicle-to-vehicle relaying, and the penetration rate of the communication technology, even in presence of large instances of the problem. Results highlight the existence of two operational regimes at different penetration rates and the importance of an efficient, yet 2-hop constrained, vehicle-to-vehicle relaying. Index Terms—Vehicular networks, downloading, optimization. I.
