摘要：Nowadays, everything is moving towards the infrastructure less wireless environment to bring the smartness of the society. In this situation, it is necessary to bring the smart technologies in the adhoc network environment. As vehicular traffic is a foremost problem in modern cities and on highway. Huge amount of time and resources are wasted while traveling due to traffic congestion. VANET is providing comfort and safety for passengers. Moreover, various transactions like information on accident, road condition, petrol bank details, menu in the restaurant, and discount sales can be provided to the drivers and passengers. The speed and time in which the message is sent and received plays an essential part in the Intelligent Transport System (ITS). For this the VANET requires efficient and reliable methods for data communication, gathering and retrieving information for seamless handoff in VANET. In this paper we discusses the architecture of VANET consists clusters that�s designed by mobile agents having instantaneous conditions of Mobile Nodes available in VANET. For efficient data communication, an attempt has been made to create a new clustering concept with the help of mobile agents among the VANET nodes. Subsequently for smooth and seamless handoff we have considered the call admission control mechanism with the help of Genetic algorithms applied over information retrieval system managed by mobile agent with the effect of shadowing for reducing the data overhead over VANET.
