  Vehicular Adhoc networks (VANETs) are composed of vehicles connected with
wireless links to exchange data. VANETs have become the backbone of the
Intelligent Transportation Systems (ITS) in smart cities and enable many
essential services like roadside safety, traffic management, platooning, etc
with vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I)
communications. In any form of research testing and evaluation plays a crucial
role. However, in VANETs, real-world experiments require high investment, and
heavy resources and can cause many practical difficulties. Therefore,
simulations have become critical and the primary way of evaluating VANETs'
applications. Furthermore, the upfront challenge is the realistic capture of
the networking mechanism of VANETs, which varies from situation to situation.
Several factors may contribute to the successful achievement of a random
realistic networking behavior. However, the biggest dependency is a powerful
tool for the implementation, which could probably take into account all the
configuration parameters, loss factors, mobility schemes, and other key
features of a VANET, yet give out practical performance metrics with a good
trade-off between investment of resources and the results. Hence, the aim of
this research is to evaluate some simulators in the scope of VANETs with
respect to resource utilization, packet delivery, and computational time.
