Description
Summary:Nowadays we have observed an increase on vehicles number on the road. This increase justifies the need for all those vehicles to communicate in order of better coordination. The dedicated vehicles communication concerns both the communication between a vehicle and vehicle V2V or even a vehicle and infrastructure V2I such as road signs and other structures on the roads. This type of communications will allow modern vehicles no longer enough to identify potentially dangerous hazards on the roads but also be able to send and receive information in interaction with their environments. The V2X communications between vehicles will provide based on the Intelligent Transportation Systems ITS two different classes of applications: applications involving road safety in one hand and applications for the ergonomics of transport in the second hand. Road safety systems, road traffic control, and other service application are vehicular systems based on new information technologies which need an efficient information transmission. Based on this theme, a multitude of research teams in the world (Japanese, American and European) are focusing on vehicular communication performances and enhancement. The main goal of this paper is to evaluate the real performance of the IEEE 802.11p in order to propose solutions and enhancements. We have conducted a set of experimentation measurements in different environments in order to evaluate the IEEE 802.11p transmission in different real scenarios. First we tried to identify the maximum range in which the communication between sender and receiver can be well done. In the second scenario, we tried to evaluate the communication between the infrastructure represented by a stopped vehicle and another moving vehicle at different speed. Finally in the last scenario, we have used two moving vehicles with different speeds in opposite directions in order to evaluate the V2V communication with high speed rate.
