Introduction

ns-3 is a discrete event network simulator and the next major revision of ns-2. The OSM mobility model is an attemp to use OpenStreetmap Data to generate mobility models for ns3 (and other network simualtors as well). Often mobility models for network similators are based on a pure random basis (a node is placed on a random position on the map and move with velocity n to position m). This is often far from beeing perfect and sometimes the mobility model have a great influence to the results.

Focus of this project:

• Provide a vehicular mobility model for VANETs (velocity, crossroad characteristics, ...)
• Utilize freely available GSM based data to cover real scenerious
• Tight NS-3 integration
• Flexible to re-use in other projects too
• Built-in graphic support to visualize the scenarios

OSM Maps

Some maps are already prepared and ready for the simulation. You can download my files or download your own area files via the openstreetmap project. If you are new to openstreetmap then I suggest to take one of these files first:

• Munich Center
• Manhattan - New York City
• San Diego

Gnuplot Files

To generate maps equal to the figures above you can use the following gnuplot file: osm,gpi. This will generate two enhanced postscript (EPS) files. You can convert these files to PDF via epstopdf --outfile=osm.pdf osm.eps. Last but not least: to convert to a pixel based graphic type convert -density 300 osm.eps osm.png
