Vehicular ad hoc networks VANETs are being increasingly advocated for traffic control, accident avoidance, and management of parking lot and public areas. In particular, communication devices are being installed in more and more cars and roadside infrastructure components. At the same time, they will have direct access to a fixed roadside network infrastructure with information flowing both ways Security and privacy are two major concerns in VANETs. Unfortunately, in VANETs, most Privacy-preserving schemes are vulnerable to Sybil attacks, whereby a malicious user can pretend to be multiple...

Wireless communication technologies have now greatly impact our daily lives. From indoor wireless LANs to outdoor cellular mobile networks, wireless technologies have benefited billions of users around the globe. The era of vehicular ad hoc networks (VANETs) is now evolving, gaining attention and momentum. Researchers and developers have built VANET simulation software to allow the study and evaluation of various media access, routing, and emergency warning protocols. The Vehicular Ad Hoc Networks Mobility Simulator (VanetMobiSim) is a set of extensions to CanuMobiSim, a framework for user...
