EVALUATING THE PERFORMANCE OF THE PHY IEEE 802.11p PROTOCOL WITH VEHICLE TO VEHICLE COMMUNICATION WITHIN AN Ad HOC VEHICLE NETWORK

Doctoral School of Science and Technics of Engineer and Innovation

Faced with the increasing number of road accidents of recent decades; Vehicular Ad hoc Networks (VANET) have become an essential technology in the realization of intelligent transport systems (ITS) to meet various demands in real time. In these networks being among the Mobile Ad hoc Networks (MANET), vehicles that tend to move in an organized manner communicate with each other, or even with roadside infrastructures that can also be characterized with a fairly high accuracy. To establish a communication in real time, the study is done on the performance evaluation of the transmission and reception protocol in a vehicular environment. In order to support ITS, the IEEE-1609 set of standards has made an amendment for Wireless Access to Vehicle Environment (WAVE) that specifies an architecture that includes new standards for vehicular communications. The IEEE 802.11p standard, which is the standard for Vehicle to Vehicle (V2V) and for Vehicle to Infrastructure (V2I) communication, constitutes the WAVE protocol stack for support and enhancement of physical (PHY) and medium access control (MAC) layers. In this article, we focus on the communication of vehicles with vehicles by evaluating after simulation that the new standard 802.11p is the optimization of the 802.11a in terms of transmitted information and packets error rate. However, there is always works which should be done to increase the execution time within that new standard.
