Abstract

For the characteristics of high speed mobility of nodes, frequent changes of dynamic topology and frequent interrupts of the communication links in the VANET, this paper analyzed the defect of the current mobile ad-hoc network routing protocol, and carried on the simulation analysis on the adaptability of AODV, DSR and DSDV routing protocols in VANET applications in the VANET. Through the above research, this paper obtained the conclusion that the AODV routing protocol is more suitable for vehicular ad hoc network environment

Highlights

In recent years, on the account of the rapid development of wireless communication technology and the urgent need in the information technology of transportation field, the VANET(vehicular Ad Hoc Networks), one important foundation concept of intelligent transportation systems, was spawned
VANET is a type of special mobile ad hoc network, which creatively applies Ad hoc network in inter-vehicle communications, allows the drivers to obtain status information of other vehicles over the horizon and real-time traffic information
For the characteristics of high speed mobility of nodes, frequent changes of dynamic topology and frequent interrupts of the communication links in the VANET, this paper analyzed whether the current routing protocol of mobile ad hoc network can meet the communication requirements of VANET or not

INTRODUCTION

On the account of the rapid development of wireless communication technology and the urgent need in the information technology of transportation field, the VANET(vehicular Ad Hoc Networks), one important foundation concept of intelligent transportation systems, was spawned. VANET is a type of special mobile ad hoc network, which creatively applies Ad hoc network in inter-vehicle communications, allows the drivers to obtain status information of other vehicles over the horizon (such as speed, direction, position, pressure of brakes plate, etc.) and real-time traffic information. Its main characteristic is the network nodes can move arbitrarily, frequent changes in network topology, and each node has the function of both host and router. For the characteristics of high speed mobility of nodes, frequent changes of dynamic topology and frequent interrupts of the communication links in the VANET, this paper analyzed whether the current routing protocol of mobile ad hoc network can meet the communication requirements of VANET or not
