    Abstract

    :

    Vehicular ad hoc networks (VANETs) enable exchange data among the vehicles and roadside access points (APs), and are essential in the intelligent transportation system (ITS) applications. VANETs support various ITS applications through different types of communication mechanisms, including vehicle-to roadside (V2R) and vehicle-to-vehicle (V2V) communications [3]. V2R communications involve data transmissions between vehicular nodes and roadside APs. vehicle-to-roadside (V2R) communications for a vehicle that aims to upload a file when it is within the APs’ coverage ranges, where both the channel contention level and transmission data rate vary over time. The vehicle will pay a fixed amount each time it tries to access the APs, and will incur a penalty if it cannot finish the file uploading when leaving the APs V2V communications only involve data exchanges among vehicular nodes. For both types, we can further classify the communications as either single hop or multi-hop. cellular networks GPRS, 3 G, provide Internet connection but expensive cost. Wi-Fi, based on IEEE 802.11, is another technology to provide wireless connectivity. Wi-Fi networks are considered as a promising technology to offload cellular networks. However, there pose many challenging problems in highly dynamic vehicular environments for Wi-Fi networks .In Existing system single AP communicate with the client due to the limited coverage of each single AP, a client suffers from frequent connection disruptions caused by handoffs and re-associations. In Proposed system the Group of APs communicate with the client to support the seamless and efficient Wi-FI based Internet access from moving vehicles. VANET is expected to significantly improve the security of our transportation systems. In This paper to analyze the security algorithm and which one is suitable for the vehicular ad-hoc networks.
