GENERAL IDEA OF VANET SIMULATION

During the planning stage, simulation has been utilized to provide a practical, cost-effective, convenient and adaptable environment for the system design. Simulation refers to a handy prototype that is transportable or the replica of whatever system is under consideration. The following are the major roles of simulation,

• Simulations – deeper analysis under different abstractions and on a large scale which can be conveniently shared and reproduced
• Testbeds- exact analysis on the performance at implementation (including constraints) is typically small scale networks
• Real-Time testing- expensive and highly realistic test which consume more time and efforts

In most cases, simulations and testbeds can be combined. To improve accuracy, we can use the MATLAB simulator for vanet based projects.Since MATLAB is being used in the context of smart (mobile) node distribution it also has a universal simulator to be used for a variety of purposes.
