557Simulation of Communications and Networking in Vehicular Ad Hoc Networks
• Modeling multiprocessor and distributed systems
• Modeling discrete event systems where entities need to communicate through the exchange
of messages or packages
Vehicular networks simulator (VNS) is one of the most recent frameworks released by OMNeT.
VNS is a simulation framework that integrates the mobility component with network component
in a transparent and efcient way, reducing the overhead of communication and synchronization
between different simulators. VNS provides bidirectional interaction between a microscopic mobil-
ity model and a network simulator. OMNeT++ is a widely used platform in the global scientic
community because it is free for academic pur ...
