Hi guys,
This vehicular sensor networks is based on AD-hoc networks it is a real time project mmm..all most completed in US & UK...in india 50% of the project is completed.
ii had sent this ppt to NIT wgl out of 256 ppts only they were selected 12 ppts..in that my ppt is 3rd one...mmm..i felt soo gud at the moment..
if ur interested u can download and add ur thoughts...in the gud manner...

Vehicular sensor netwks ppt

  1. 1. Vehicular Sensor Networks ... Kaduru Venkatesh
  2. 2. OVERVIEW OF VEHICULAR SENSOR NETWORKS∗ INTRODUCTION∗ ARCHITECHTURE∗ NETWORKING PROPERTIES∗ APPLICATIONS∗ CONCLUSION
  3. 3. INTRODUCTION∗ The rate of accidents on highways has been growing in an ascending mode, as per the report of the national high way traffic safety administration (NHTSA), in us only vehicles crashes on the highways resulted in the loss of 40,0000 lives.∗ It was therefore, necessary to give better safety.∗ In previous decades passive safety systems like safety belts, airbags were widely used.∗ After that abs(anti brake system), esp(electronic stabilty programs) are being used.
  4. 4. ∗ The Important Components Of Its (Intelligent Transportation System) Is VANET (Vehicular ADhoc Network) In Which Vehicles Are Equipped With Short Range And Medium Range Wireless Communication∗ Here we have two kinds of communication 1. v2v(vehicle to vehicle ) 2. v2i(vehicle to roadside units).
  5. 5. Architecture∗Mobile sensor nodes: these are embedded onboardvehicles∗Stationary sensor nodes (rss) : They are deployed in apredetermined distance beside the road.∗Base Stations : They are police traffic control checkposts, fire fighting stations etc…
  6. 6. RSS96 RSS98 RSS100 RSS102 ACCIDENTRSS97 RSS99 RSS101 SCHEMATIC VIEW OF ACCIDENT CASE
  7. 7. GPS signals are under the effect of the following whichattenuate them: ∗ Delay of troposphere and ionosphere ∗ Orbit errors ∗ Obstacles : Buildings , trains etc.. Hardware constraints: ∗ Dependency on GPRS system online ∗ Less accuracy ( upto 15 meters in positioning and 0.5kmph for velocity)
  8. 8. Applications: Safety Applications: ∗ Velocity monitoring ∗ Accident notification ∗ Cooperative collision avoidance Convenience Applications: ∗ Congested road notification ∗ Electronic penalty bill Commercial Applications: ∗ Roadside advertising and marketing
  9. 9. Conclusion:With respect to the future works on this proposal , the rateof accidents and followed by it the number of causalitiesand injuries will be reduced
