Vehicular networking is one of the research areas which need to be addressed because of its features and some of the applications such as consistency, capable traffic management. Many works have been done to address the various issues of vehicular networks and various technologies have been implemented to for the maintenance of Intelligent Transportation System (ITS). One of the major issues that we are addressing in Vehicular networking is Offloading scheme. A new Era in VANET has been came into picture i.e., the introduction of the concept of wifi Offloading .Here, smart phone users are rapidly rising day by day. So, the main benefit of having the smart phone is that they can easily access the network at wherever, every place. So, there is an increase in the data traffic of the service providers as the user wants to have instant access of the internet. A Recent survey By CISCO has told that Global mobile data traffic will double every year throughout 2014, growing 39 times between 2009 and 2014. To overcome this heavy traffic the service providers have been introduced a complementary technology called as an Offloading scheme through wifi, WiMax technologies. © 2015 The Authors.
