How to set up NS3 for VANET? Implementing NS3 Vanet simulation

Vehicular communication systems are intended to enhance the intelligent transportation system (ITS) utilizing reliable communication among vehicles with roadside units (RSUs). In VANET, it connects the vehicles with other interacting nodes such as vehicles, RSUs, pedestrians, or surrounding objects. From the viewpoint of ITS or VANET, it shares the information either inside or outside of the network in both cases of normal and emergencies.

For instance, safety warnings, traffic/parking information are developed nowadays as ITS applications. Overall, it provides the best services for infotainment, traffic efficiency, highway safety, smart transportation, etc.

This page brings out more information on NS3 VANET simulation with their latest research modernization!!!

Because of the enriched characteristics of VANET as mobility and self-directing, it gains more attention in the research community. And, it motivates both academic individual and master researchers to conduct research and experiments in big/small scale vehicular communications.

Why simulation is required for VANET?

When we work on a big-scale network, it is important to assess the performance and efficiency of the application in the distributed system. For example, if someone is working on traffic management in a metropolitan network, then the network must focus on the security and routing protocols in current research. Compare to simulation, real-world implementation is expensive and practically hard to assess the protocols for big-scale networks.

Overview of NS3 in VANET

In fact, NS-3 is a popularly used discrete-event-based network simulation tool for developing VANET applications and services. Majorly, it supports different protocols which are capable to support huge nodes and network traffic. More than the other simulators, NS-3 provides high performance.

Generally in VANET, the nodes will freely and randomly move their position to interact with the surrounding neighbors in the coverage area. So, it is essential to find which node will receive the packets at the time of wireless transmission. Most importantly, we need to accurately predict the accessible nodes for efficient packet forwarding.

First and foremost, our research service is very precise in delivering novel VANET systems. Since we usually upgrade our knowledge on both current and future research technologies. Once you make a bond with us, let you find answers for the following questions,

What are the topics currently available in your interested VANET areas?
What is the procedure to configure the desired scenario for various environs?
By what means, we need to define a scenario for VANET assessment?

Research Challenges of NS3 in VANET

In recent times, the simulation of the huge-scale network is quite a challenging process, particularly in VANET developments. If you are dealing with a huge network, then it is necessary to concentrate on communication protocols design for any kind of application. Since the handling of large-scale nodes in real environs is a tedious process. So, the simulation process needs more concern for selecting appropriate methodologies.

Though the NS-3 tool is widely used for several applications development, it is lacking in scalability which results in constrained performance. So, it gives the best result in the medium-sized network. For increasing the understand ability, here we have given you the list of network operations and entities that are required for building VANET scenarios.

What are the components used for VANET scenario creation?

Network Routing Protocols Ad-hoc Routing Standards

Next, we can see how the VANET environment is designed and configured in NS3 Simulator. Here, we have given the key points to create scenarios, deploy nodes, choose mobility models, and more. And, this is common for general VANET projects in NS3 further it may vary based on project needs.

In the simulation framework, configure the all-important parameters required for designing and developing network models using the config attribute in the NS-3 module. Some of the parameters are system bandwidth, buffer size, RLC type, carrier frequency, etc. And, we can also decide whether AMC is required or not depends on the parameters.
