Vanet Vehicular Ad Hoc Network Projects network aims to develop safety systems for drivers and pedestrians in vehicular environs. Our VANET Project Help Team has the aim to give long-lasting support for research fellows who wish to carry out their research on the transportation system. This network is majorly designed with a set of moving and static vehicles along with walkers on the roadside. And also, it incorporates Road Side Units (RSUs) as the base station, access point, etc. 

On the current page, we are going to express the research perception of VANET with comprehensive reference. For that, our vanet research panel team brings up a detailed explanation of VANET basic architecture, sensational research issues, and methodologies. And also, we extended our backing support in safe driving, intelligent navigation, and emergency and entertainment applications.

What is VANET?

In recent days, Vanet Vehicular Ad Hoc Network Projects is found to be one of the worldwide growing research fields. It is popularly referred to as an intelligent unit of the Transportation Systems. In this, it launches the communication between all kinds of vehicles as well as with roadside units placed at the crucial point of highway like a crossroad, junction, etc. At the present time, most of the recent research is committed to VANET. 

Most probably, VANET offers safety and ease to every vehicle driver and pedestrian through V2V communication. For instance, it offers a service of delivering warning messages in the case of heavy traffic to minimize road accidents and traffic jams. Besides, it works on the collection of existing traffics scenarios. In VANET, each IEEE standard has a separate set of operations to perform. And, here we have shown you few important standards in VANET communication.

IEEE Standards for VANET Communication

  • IEEE std 1609.1 (WAVE Resource Manager)
    • Functions – Permission for the interaction of OBUs and outside of the OBUs
  • IEEE std 1609.2 (WAVE Security Services)
    • Functions – Security for secure messages, processing and data exchange
  • IEEE std 1609.3 (WAVE Networking Services)
    • Functions – Services of Routing and Networking
  • IEEE std 1609.4 (WAVE Multi-channel Operation)
    • Functions – Operations of Multiple Channels
  • IEEE std 802.11p (WAVE PHY and MAC)
    • Functions – Let Operation in rapid changing VANET environs

In the above bulletins, WAVE is mean for Wireless Access in Vehicular Environment, MAC is means for Medium Access Control and OBU is mean for On-Board Unit.

What are the Communication Ranges in VANETs?

In general, Vanet Vehicular Ad Hoc Network Projects (Vanet Communication) is classified as V2V (Vehicles to Vehicles) and V2I (Vehicles to Roadside Nodes). Further, communication technology is partitioned into three important ranges based on distance.

  • Long Range – Cellular, WiMAX and MBWA
  • Medium Range – Wi-Fi, DSRC/WAVE, CALM
  • Short Range – Infrared, Bluetooth and ZigBee, UWB

For instance, here we are going to describe to you the operations of the Dedicated Short-Range Communications (DSRC) protocol. By the by, it is employed to exchange safety messages in both V2V and V2I networks with high data rates and low latency in the communication link.

How does DSRC protocol works in VANET?

Intending to ensure safe and reliable transmission, the DSRC functions on the below-specified channels. For example, the Federal Communication Commission (FCC) allotted 75MHz Spectrum in 5.9 GHz band for V2V and V2 I communication.

Spectrum of DSRC

  • SCH Type
    • Frequency (MHz) – 5.860, 5.870, 5.880, 5.900, 5.910, 5.920
    • Channel – CH 172, CH 174, CH 176, CH 180, CH 182, CH 184
    • Purpose – IP data, WSMP with low priority
  • CCH Type
    • Frequency (MHz) – 5.890
    • Channel – CH 178, CH 174
    • Purpose – Control data, WSMP with high priority

Now, we can see about services essential for DSRC protocol. Majorly, the services may fall under categories of periodic and event. Also, the services will vary based on packet size, maximum transmission delay and transmission range e.g., for vehicle signal contains 100 bytes packet size, 1000 ms maximum transmission, and 300-1000m transmission range.

Message Transmission in Vanet Vehicular Ad Hoc Network Projects

Periodic

  • Intersection Collision Warning
  • Cooperation Collision Warning
  • Traffic Light Speed Advisory/Violation
  • Work Zone Warning
  • Emergency Vehicle Warning
  • Announcements
  • Speed Limited Notification

Event

  • Collision Warning
  • Vehicle Signal
  • Toll Connections
  • Lane Change Assistance
  • Motorcycle Approaching Indication

Wireless Communication in VANET

In VANET, numerous wireless access technologies are deployed by vehicles to create communication over other vehicles and base stations on the roadside. Since, this communication has come a crossed more revolutionary advance as 1G, 2G, 3G, and so on.

  • 1G (First Generation) – Data transmission is based on analog signal
  • 2G (Second Generation) – Data transmission is based on digital signal. And, it also supports add-on services as below,
    • Global System for Mobile communications (GSM)
    • Digital AMPS (D-AMPS)
    • Code-Division Multiple Access (CDMA)
    • Personal Digital Communication (PDC)
  • 2.5G – It is the combination of GRPS and GSM which is capable of 170Kbps data transmission speed with internet access. Then to increases the data rate up to 384kbps EGPRS can be operated on any GSM frequency band.
  • 3G (High-speed Downlink Packet Access) – It is suited to 14.4Mbps data transfer speed.
  • 4G/ LTE (Long Term Evolution) – It is allowed 129Mbps data transfer speed that practices the 1700 MHz and 2100 MHz frequency bands. In addition, it contains novel standard as WiMAX Mobile (IEEE 802.16m) that follows advanced modulation techniques for mobile users’ broadband access. The methods are as follows,
    • Adaptive Modulation and Coding (AMC)
    • Hybrid Automatic Repeat Request (HARQ)

Channel Model is one of the essential concepts in VANET communication.  And there are several channel models available for communication channel. Now, shall we see about very few models that are currently being used in simulation of VANET.

Implementing Vehicular AD Hoc Network Projects

What are the channel models for VANETs simulation?

  • Unspecified: Absence of channel model particulars
  • Log-Normal: A log normal fading / shadowing model by means of distribution
  • Two-Ray: Compare to FSPL, a pathloss model is more sophisticated, direct path modelling and a single ground reflection.
  • Nakagami-M: In urban infrastructure, this fading model gains more familiarity for communication. At that time, it undertakes one transceiver at a higher elevation part from others. As a result, this model is well-matched for cellular networks
  • Static RTX: A risky transmission ranges from very long distance which are unable to interact
  • Custom Models: Designing own channel models based on requirements. Whereas, it grasps the brief description of its principles.
  • Friis Free-Space Path Loss (FSPL): It is a user-friendly deterministic channel model, with one direct dedicated link among source and destination. And also, Friis channel model with statistical extensions is used to assess some published algorithms to imply fading and shadowing

Now, shall we see about very few models that are currently being used in the simulation of VANET
