  1. HYBRID ROUTING PROTOCOL FOR VANET PROJECT GUIDE Mr.R.RAJADURAI TEAM MEMBERS S.Srinivasan R.Venkatesh M.Vinoth

  2. AGENDA • Introduction • Application of VANET • Components of VANET enabled vehicle • Vehicular Communication • Current Research • References

  3. DOMAIN - NETWORKS • A computer network is a collection of two or more computers linked together for the purposes of sharing information, resources, among other things. • These Sharing is done by using Protocols. • A communications protocol defines the formats and rules for exchanging information via a network. • Networks may be classified according to a wide variety of characteristics such as medium used to transport the data

  4. What is VANET ? • VANET – VEHICULAR AD-HOC NETWORK. • A VANET, is a technology that uses moving cars as nodes in a network to create a mobile network. • It’s an emerging new technology to integrate the capabilities of new generation wireless networks to vehicles. • Where the each vehicles are considered as a nodes or router for communication that occurs approximately 100 to 300 meters. • “VANET make transportation systems more intelligent”

  5. Applications of VANET • Safety Application • Slow/Stop Vehicle Advisor (SVA). • Emergency electronic brake-light (EEBL) • Post Crash Notification (PCN) • Road Hazard Control Notification (RHCN)

  6. Cont.. • Convenience Application • Congested Road Notification (CRN) • Parking Availability Notification (PAN) • Commercial Application • Service Announcements (SA) • Content Map Database Download (CMDD) • Real Time Video Relay (RTVR)

  7. Protocol used in VANET • AODV (Ad hoc On-Demand Distance Vector) • OLSR (Optimized Link State Routing Protocol) • DYMO (Dynamic MANET On-Demand) • DSRC (Dedicated Short Range Communication) • CALM (Cont Air interface for Long & Medium distance) • CVIS (Cooperative Vehicle-Infrastructure System) • OFDM (Orthogonal Frequency Division Multiplexing)

  8. Schematic Representation of a VANET

  9. Components of VANET enabled vehicle • It include computer controlled devices and radio transceivers for message exchange. • The Standard protocol DSRC(Dedicated Short Range Communication), which has a communication range of 300 mts to 1 km. • The DSRC is performed by using MAC (Medium access control).

  10. Vehicular Communication • VANET communicates through Wireless Access for Vehicular Environments (WAVE). • The WAVE uses different types of Wireless Commutation devices such as (WiFi / WiMax). • The sensors or wireless devices can form a VANET network which resides on top of the vehicle.

  11. Cont.

  12. Communication using FM • The U.S. Federal Communications Commission (FCC) recently allocated 75 MHz of DSRC spectrum at 5.9 GHz to be used exclusively for V2V and V2R communications.

  13. vehicle-to roadside communications (V2R) Vehicle-to-vehicle communications (V2V)

  14. Current Research • A Survey - Routing in Vehicular Adhoc Network • Performance Evaluation of AODV, OLSR and DYMO Protocols for VANET. • Dynamics of Network Connectivity in Urban Vehicular Networks • A Secure Vanet Mac Protocol For DSRC Applications • A Novel Rsu-based Message Authentication Schema For Vanet

  15. FutureTrends • Expansion of roadway capacity has not kept up with the growth in travel in the United States, causing significant increases in congestion in major urban areas. Nonrecurring congestion created by crashes or other incidents is a major component of delays experienced by drivers in urban areas. • Most traffic data is currently collected using a network of point detectors, such as inductive loops, microwave radar sensors, or video detection systems.

  16. Cont.. • DOTs use data for a wide variety of purposes, including characterizing travel on links, providing real-time monitoring and control, and controlling traffic signals on urban streets. • The type and quantity of traffic data available varies depending on where the data is collected. Major urban freeways tend to have closely spaced sensors that provide real-time data for traffic management.
