What is VANET?
The vehicular ad hoc network is abbreviated as VANET and it is the compression in of self-organizing vehicles as the mobile nodes. In addition, VANET is providing the comprehension for vehicle to road side (V2R) and vehicle to vehicle (V2V) to develop the comfort and safety measures such as lane changing assistance, traffic optimization, collision avoidance and more.
What is Ns3?
The Ns3 is one of the simulation tools which is used to develop the open source and free simulation environment that is apt for the process of networking research and that is associated with various simulation requirements in the modern networking research. In addition, it should embolden the software validation, peer review and contribution of the community.
Most significantly, our technical experts have highlighted the list of security necessities and the issues in security which is relatable for the VANET simulation in Ns3 in the following.
Security Requirements and Challenges for VANET
- Vehicle tracking
- In vehicle safety and vehicle tracking, the exact location of the vehicle is considered as the most significant data. In addition, the notable challenge to secure the scheme of communication of VANET faces includes the depiction of balance among the nonrepudiation versus privacy and authentication
- Evidence and proof management
- While the vehicle is moving on roads and highways, the concerns have to identify the vehicle in case of illegal travel speed that might cause accidents and on the other hand some services needs the proofs
- Responsibility enforcement
- Vehicles have to provide information to recognize the accountability acknowledgment. For instance, in the accident cases the authorities are entitled for the documentation of accountabilities
- Accessibility
- Vehicular system includes the long lifetime and the suitable performance of sensitive subsystems have to be confirmed all the way through the lifecycle of vehicles
- Privacy
- Vehicular systems are considered as the private devices and the operations are directed through the regulations and practices. The privacy of driver and passenger has the high importance and that is one of the security aspects
- Access control
- In general, the vehicle systems are based on the transport means and that have to be appropriate to the individuals and legal entities
- Even more secure means are essential to control the system access
- Confidentiality
- While exchanging the information, the confidentiality have to be ensured in all the vehicle systems
- Sensors
- GPS
- OBU
- RSU
- It is the most significant process and the authorized persons only can access the data particularly in V2I and V2V communications
- Integrity
- The information and data are distributed from several resources of information and that should not be modified through the attackers. The appropriate data from various sources have to be safeguarded against the unauthorized falsifications and the sources such as
- V2I communications
- V2V communications
- SU systems
- Sensors
- RSU
- OBU
- Authentication
- It is process used to verify the identity of vehicles and drivers. In addition, the frames of beacons are authenticated to avoid the spoofing attacks
Channel Congestion control in VANET
The process of VANET simulation in Ns3 includes the three significant types of congestion control in VANET. So, our research professionals have enlisted the three types in the following with their significant characteristics.
- Hybrid control of transmission power and rate
- The rate of transmission and power control are used to obtain the acceptable accuracy for tracking the nearby vehicles through avoiding congestion in the shared commutations channels
- Power control is deployed as the linear function set among the minimum and maximum power constrains based channel load and it is measured through the clear channel assessment functions
- Beaconing rate control
- Adaptive traffic control is the demonstrative technique in TRC scheme and it is sued to determine the period of beacon transmission that is related to the utility of message and quality of channel
- Transmit control is used to control the beaconing period and this the technique which includes various effect in the beacon reception rate
- Transmission power control
- Beaconing rate control is capable to lead the potential lack of data and that is capable to impend the safety of vehicles due to the reduction of beaconing rate in the congested circumstances
Additionally, our technical experts in VANET have enlisted the advantages based on vehicular ad hoc network simulation in Ns3.

While using the Sumo packages and Ns3 network simulator to transmit and receive the packets among the participating cars with three ad hoc routing algorithms such as DSR, DSDV and AODV. So, we have enlisted the significance of routing process in VANET with the utilization of Ns3
Routing in VANET using Ns3
- Modeling communication network using Ns3
- Physical layer up is used to diverse the application layer protocols and the routing algorithms in Ns3. The simulation for 3 cars is selected as the sender and the data packets are leads to reach the 3 cars as the receiver. The rest of the process is in the intermediate forwarders. The simulation process adopts TCP and UDP transport layer protocols and the ad hoc routing protocols such as DSR, DSDV and AODV
- Modeling car traffic flow using SUMO
- Sumo is considered as the open source project including various parts of the car and that is individually modeled to move the cars in frequent space at the discrete time. It is capable to model the traffic lights, cars, diverse roads and etc. This process includes three information for the traffic flow simulation and they are
- Flow data to depict the process of car moving from one node to another in what average speed
- Indication of edge data lanes of roads and directions
- Node data consist the intersection and junction of roads
