NS3 Vanet Projects

Implementing NS3 Vanet Projects

Vanet referred as vehicular Ad hoc Network is used for short range wireless communication. VANET is a self organizing, decentralized, and infrastructure less network unlike Wimax, Wi-Fi and GSM technology. We Provide guidelines with source code for implementing NS3 Vanet Projects with best support within stipulated time.

Applications of NS3 Vanet Projects:

  • Mobility modeling.
  • Dynamic topology.
  • Road traffic safety.
  • Frequent disconnections.
  • Predictable mobility patterns.
  • Traffic efficiency.
  • Comfort and quality of road travel.
  • Stringent delay constraint.

Challenges Faced in NS3 Vanet Projects:

  • Provisioning of QoS.
  • Bandwidth consideration.
  • Individual privacy among vehicles.
  • Security to vehicle.
  • High connectivity among network.
