VANET SIMULATION NS3 PROJECT

VANET SIMULATION NS3 PROJECT , the nodes are communicated using the IEEE 802.11p standard for wireless communication. Vehicles connected to each others through an ad hoc formation form a wireless network called as Vehicular Ad Hoc Network. VANETs are a subgroup of the MANET

Characteristics of VANET:

Unbounded network size
Crucial effect of security and privacy
Have high mobility of nodes
Real-time, time-sensitive data exchange
Rapidly changing network topology
Potential support from infrastructure etc.

Architecture of VANET:

Challenges Faced in VANET SIMULATION PROJECT:

Network scalability
Mobility
Privacy Vs liability
Volatility

Privacy Vs authentication

Sample code for Vanet Simulation NS3 projects :

This is the sample code for vanet routing compare.
