دانلود Survey over VANET Routing Protocols for Vehicle to Vehicle Communication

Abstract

VANET   (Vehicular   Ad-hoc Network)   is   an   emerging   new   technology   with   some   unique characteristics that makes it different from other ad hoc network. Due to rapid topology changing and frequent disconnection it is also difficult to design an efficient routing protocol for routing data among vehicles, called V2V  or  vehicle to  vehicle communication  and  vehicle  to  road  side infrastructure, called  V2I. Because of  road accident  daily  occurrence  VANET  is  one  of  the  influencing  areas  for  the  improvement  of  Intelligent Transportation  System (ITS)  which  can  increase  road  safety  and  provide  traffic  information  etc.  The  existing routing  protocols  for  VANET  are  not  efficient  to  meet  every  traffic  scenarios.  Suitable  routing  protocols  are required  to  establish  communication between vehicles in future for  road  safety.  In  this  paper,  we  focus  on  the merits  and  demerits  of  routing  protocols  which  will  help  to  develop  new  routing  protocols  or  improvement  of existing routing protocol in near future.
