VANET Simulation in NS2

VANET simulation in NS2 is widely used to study the transmission of information between moving vehicles in a network. Vehicular Ad-hoc Network (VANET) is considered a special type of mobile sensor network that is characterized by high mobility and frequent topology changes.

In VANET, each moving vehicle acts as a mobile node with the ability to sense and exchange various types of data such as speed control, environment monitoring, traffic updates, and locating lost vehicles. As an emerging technology, VANET simulation in NS2 is one of the best choices for students and researchers to model and analyze real-time traffic networks.

Communication in VANET

Vehicles in VANET can communicate with each other within a specific range. The communication occurs in two main ways:

• Vehicle to Infrastructure (V2I): Vehicles communicate with roadside units (RSUs) which act as base stations for data collection and traffic control.
• Vehicle to Vehicle (V2V): Vehicles exchange information directly with each other to ensure road safety, cooperative driving, and congestion management.

This communication framework helps in safe traveling by avoiding accidents, reducing congestion, and supporting efficient navigation. Similar to GPS, VANET enables drivers to receive real-time alerts and guidance during their journey. By simulating these scenarios in NS2, researchers can test VANET protocols in a realistic environment.

Benefits of VANET

• Cooperative driving and collision avoidance
• Real-time information sharing
• Internet access, navigation, and entertainment services

• Sensing and monitoring technologies

Example of VANET Simulation in NS2

An example scenario is vehicle-to-infrastructure communication, where moving vehicles send information to roadside units (RSUs). The RSUs act as controllers, regulating traffic and ensuring road safety, as illustrated below:

The above simulation demonstrates how roadside units manage vehicles effectively within the network. We provide complete support for B.E, M.E, and Ph.D. scholars in simulating VANET projects using NS2, including coding, implementation, and research paper guidance.
