A simulation based study to implement Intelligent Transport Systems concepts in VANETs using AODV routing protocol in NS2

The wireless medium plays a vital role in communication era in sharing information from one mobile device to another. These wireless devices (nodes) can form a temporary network called Ad-hoc network or they can use existing cellular network. Vehicular Ad-hoc Networks (VANETs) is a type of Ad-hoc network in which vehicles acts as nodes and communicates with the roadside units. VANETs are more helpful in implementing the Intelligent Transport Systems concepts to provide traffic situation, weather conditions and to perform safety warnings by using authentication mechanisms. In this paper, AODV routing protocol is used to implement the Intelligent Transport Systems (ITS) concepts in VANET. A simulation is performed using AODV routing protocol in NS2 to study the hurdles involved in providing a secure and trustworthy data transfer between the vehicular nodes. The data analysis is done based on the results collected from the simulation environment. The data's are traced out to find the absolute details of the network. Finally, the graphs are plotted for Throughput of dropped packets and Throughput of packets generated.
