  Vehicular ad hoc network (VANET) is an integral part of vehicular
communication. VANET suffers many problems such as scalability. To solve
scalability and other problems of VANET, clustering is proposed. VANET
clustering is different than any other kind of clustering due to the high
mobility of the vehicles. Likewise, VANET and VANET clustering, VANET simulator
requires some unique features such as internet based real-time data processing,
huge data analysis, the complex calculation to maintain hierarchy among the
vehicles, etc.; however, neither web based VANET simulator nor clustering
module available in the existing simulators. Therefore, a simulator that will
be able to simulate any feature of VANET equipped with a clustering module and
accessible via the internet is a growing need in vehicular communication
research. At the Telecom and Network Research Lab (TNRL), University of
Oklahoma, we have developed a fully functional discrete-event VANET simulator
that includes all the features of VANET clustering. Moreover, the cloud based
VANET simulator (CVANETSIM) is coming with an easy and interactive web
interface. To our best of our knowledge, CVANETSIM is the first of its kind
which integrates features of the VANET simulator, built-in VANET clustering
module, and accessible through the internet.
