Download GEMV2 v1.2 — now including V2I communication (see what else is new): 

GEMV2 package contains the following:

  1. GEMV2 code.
  2. GEMV2 license.
  3. GEMV2 User Manual.
  4. Dataset collected via aerial photography, containing buildings and vehicles in the city of Porto, Portugal, obtained through the DRIVE-IN project. This dataset is highly precise and can be used as a starting point for the simulations.
  5. Since Porto dataset contains only a single time-step, in addition to it, packaged with GEMV2 you will find building and foliage outlines extracted from OpenStreetMap, and SUMO mobility for the following cities:
    • Part of downtown Cologne, Germany. For vehicular mobility in Cologne, the package contains a preprocessed SUMO file generated using “TAPAS Cologne” scenario. Running GEMV2 with this dataset results in 100 simulated seconds.
    • Dataset with 20 simulated seconds in Newcastle, UK.
    • Dataset with 50 simulated seconds in Bologna, Italy. This dataset contains both V2V and V2I communication.

  • Includes a set of new V2I propagation models, which were validated using V2I measurement traces collected by Uwicore Laboratory (available here). The paper describing V2I modeling and simulation will be available soon. For the time being, if you would like a copy of the paper, please send an email to Bengi Aygun (baygun at
  • Added a new sample SUMO/OSM dataset (Bologna) that can be used to simulate both V2V and V2I communication
  • Numerous bugfixes (special thanks to Ioannis Sarris and Nikos Kanistras @ U-Blox!)
  • Simplified parameter input and scenario setup for running simulations
  • Tested on Mac OS X El Capitan with Matlab 2013a and 2014a, Windows 7 with Matlab 2014a & 2015a, Ubuntu 14.04 with  Matlab 2014a & 2015a


  • Added neighborhood size calculation and visualization
  • Added output file containing number of communication pairs per timestep
  • A new sample dataset (Newcastle)
  • Bugfixes
  • Improved documentation
  • Clearer description of key variables
