Efficiently Design for Cross Layer Optimization Using Handover Scheme in Vehicle Adhoc Networks

In the world of internet and more use of wireless technology, there is increasing claim for internet in vehicles. Due to this purpose VANET is playing an important part in inter-vehicular as well as infrastructure based communication in Intelligent Transport Systems (ITS). These systems are aimed at addressing critical issues like passenger safety and traffic congestion, while integrating information and communication technologies into transportation infrastructure on vehicles. They are built on top of self-organizing networks, known as a vehicular Ad hoc Networks (VANET), composed of mobile vehicles connected by wireless links. In high speed roadways WiMAX Mobile Multihop Relay (MMR) is playing an important part in VANET for vehicles. We can have certain vehicles as Relay Vehicles (RV's) which can provide internet access to oncoming vehicles or other passenger vehicles. Since we do not know how far a RV is or when it is going to arrive, we require a fast handover technology so that a lot of contrary due to delay can be reduced. In this paper we are going to analyze the connectivity of Dense and Sparse network using Cross Layer vehicular Handover Scheme in VANETS, also we are going to tell some main issues over security among the inter-vehicular communication and synchronization between RV's. So, we can optimize the connectivity in cross layer vehicular ADHOC networks.
