Vehicle to Vehicle Cluster-Based Auto-Configuration for Vehicular adhoc Networks

The auto-configuration for Vehicular adhoc networks remains a challenging issue, where the traveling vehicles (nodes) are not bound to travel only in restricted regions like MANET. The application of auto-configuration in infrastructure-based seems to be easier issue as compare to network ad hoc mode. In the ad hoc network, configuration of IP address in advance is not considered a practical method. Nodes need to be configured on fly or at run time. In VANET the Vehicular Address Configuration (VAC) protocols, claimed to be first protocol to consider auto-configuration protocol to reflect on the ad-hoc mode of VANET, but the VAC remained victim to frequent re-configuration request of IP address. This paper introduces Cluster-Based Auto-Configuration (C-BAC) protocol for VANET in ad hoc mode environment. The C-BAC applies lane and speed based grouping algorithm in order to achieve better result. The traveling vehicles on highways adjust to traveling group according to their traveling cluster. This clustering of vehicle according to speed and lane grouping stabilizes the network and reduces request re-configuration requests immensely. In simulation result C-BAC outperforms the VAC protocol, as C-BAC stabilizes the network and reduces the frequent re-configuration of IP requests.
