Dynamic auto node configuration with Adhoc features is an advanced concept for vehicle communication. It is the modern internet-based data transmission in Intelligent Transport Systems. Different node auto-configuration schemas and node address-related approaches were used to improve network infrastructure and robust data communication between vehicles in Transport Intelligence-based wireless vehicle Adhoc networks. To address the problem of vehicle node auto-configuration with reduction of delay in transmission is an emerging research concept in data forwarding between vehicles in Adhoc networks, so this paper proposes an Automatic Dynamic User Allocation based Data Forwarding with Opportunistic Routing (ADUADFOR) approach with the assistance of mobility of vehicle association concerning the forwarding of data between vehicles in Adhoc networks. In this approach, each vehicle node carries a replica of other vehicle information, which decides the route based on this collective dynamic information of vehicles. Extensive simulated results of the proposed approach give better performance to improve Quality of service (QoS) through decreased overhead when compared to traditional mobility-based routing calculation methods in vehicle Adhoc networks.
