VANET (Vehicular Ad-hoc NETwork) is a wireless network technology that uses vehicles as mobile nodes to exchange data without the need for a Central Access (CA) point, which is used for safety problems. In this, the vehicles (node) transmit data about traffic and road conditions. Because of the latest advances in information technologies, it is now important to take the first step toward using software to evaluate this network prior to deployment. By implementing the network in a real-world environment, we can use simulation software to perform a detailed review of it. There are various network simulators, each with its own collection of features that set it apart from the others. We should concentrate on finding the right alternative that yields the best outcomes. NS2 is the most commonly used simulator tools; in this paper, we used NS2 to build the VANET, which allowed communication between nodes using AODV routing protocols. By changing the number of vehicles when applying TCP traffic, we use routing protocols (AODV) for various standard metrics, such as Cumulative Sum of Packet, throughput, jitter, and packet loss. The simulation was carried out using the NS2 simulation tool. Different mobility models would be considered in order to make the network situation more realistic. In this paper, we used Five forms of mobility patterns using 10, 20, 30, 40, and 50 vehicle nodes. On NS2, we drafted a TCL script to verify the affectations of the routing protocols used in the VANET. After successfully run, we conclude that the Cumulative Sum of Packet gets less forwarded to the destination, throughput is high in case of sent Packet, Jitter gets stable at last, and the most important is that there is no loss of any packet from Source to Destination.
