I have just posted an updated VANET simulator for ns-3. The previousversion (created by Arbabi), supported only one Highway. The newversion supports multiple Highways connected together inintersections, as well as creating and managing traffic lights. Thecode was developed and tested in ns-3.9. The google code poject is located here: http://code.google.com/p/ns-3-highway-mobility/ The wiki page describing installation and simple run is here: http://code.google.com/p/ns-3-highway-mobility/wiki/HighwayMobilityAndVehicularNetworksInNs3 The code can be directly downloaded here: http://code.google.com/p/ns-3-highway-mobility/downloads/detail?name=vanet-highway-version2.zip&can=2&q= The zip download includes documentation, including the Master's paperwhich covers the Architecture as well as an Examples folder whichincludes two XML configurations for use as examples. Examples alsoincludes an XSD document describing the XML format. Also available (but in beta), is a VehicleViewer utility. Thenetbeans project and all necessary jars can be downloaded here: http://code.google.com/p/ns-3-highway-mobility/downloads/detail?name=VehicleViewer.zip&can=2&q= See the included readme for basic usage instructions.
