Analysis of realistic Channel Models for VANETs (PDF paper)

• Advisors: Dr. Oznur Ozkasap; Dr. Sinem Coleri Ergen

• Comparison of

  • Simplistic and easy to implement Unit Disk and Log Normal Model with

  • Complex and hard to implement Obstacle Based Model

• Realistic Microscopic Simulation generated using

  • Simulator SUMO

  • Database PeMS Database

  • For highway traffic schenarios

• Unit disc Model:
  In unit disc model, the vehicles can communicate with each other if they are within a threshold distance and cannot communicate otherwise.

• Stochastic Large-Scale Fading Model:
  Stochastic large-scale fading model aims to take average of the additional attenuation caused to the obstacles. The resulting distribution of these variations has been found to be log-normal

• Obstacle Based Model:
  Obstacle-based channel models propose mechanisms to incorporate the effect of the surrounding obstacles, such as other vehicles, walls and buildings, on the received signal strength, rather than averaging the additional attenuation due to these obstacles using stochastic large-scale fading model.
