Analysis of End-to-End Delay in Vehicular Networks

Vehicular Ad Hoc Network (VANET) is a sub class of mobile ad hoc net-works. Currently, car to car communication is a very demanding area of research because of the numerous application possibilities for driver safety and comfort. The earlier VANET models discussed only the communication among vehicles through the RSU used for low network density. Most of the researchers used standard 802.11 for VANET model considering the mobile nodes of the city environments when network density demands. Without using the RSUs, each vehicle in the network is treated as a router to communicate with the neighbouring vehicles. The performance of communication entirely depends on how better the routing takes place in the network. Routing of data always depends on the routing protocols being used in network. An effective routing protocol for vehicular ad-hoc networks (VANETs) should have decent performance regardless of the status of the network. When the network is sparse, routing protocol should work in a way to increase chances of delivery. On the other side, when network density leads to uninterrupted connection, routing protocol should always choose a policy to minimize delivery delay. I have to create a network which should be reliable secure and fast. Reliable by using back off counter, secure by using AES algorithm and fast by using increasing the transmission power at the time of low signal strength. Packet Delivery Ratio, End To End delay, Through Put and packet drop are the metrics used for performance analysis of MIN forwarding strategy with VADD protocol.
