Comparative Study and Improvement of the Routing Protocols Used in the Vehicular Networks and v2v Communications

Abstract

VANET network is a communication network between smart vehicles equipped with several equipment such as calculators, network devices and different types of sensors when we talk about a network vanet it can also be referred to Vehicle-to-vehicle communication (V2V) in fact V2V is a technology that makes our transportation systems smart. Among the advantages of this system it can avoid accidents and traffic, V2V communication connects vehicles to each other in order to exchange data that also has the potential to avoid a crash and avoid traffic jams, Various routing protocols for VANETs and V2V communication have been recently proposed, such as Ad hoc On-Demand Distance Vector (AODV) routing protocol which is topology based and Greedy Perimeter Stateless Routing (GPSR) protocol which is geography-based, this paper compares routing protocols based on topology and position-based routing protocols and a comparative study between the various protocols such as AODV, DSR, DSDV, OLSR, ZRP and GPSR, thus, this article propose improvements on various protocols based on their weak points such as AODV, DSR and GPSR.
