DSRC, its Future and the Project
Cooperative Intelligent Transport System (C-ITS) technology enables a wide variety of vehicular ad hoc networking applications, including collision avoidance, road hazard awareness, and route guidance. Based on the Medium Access Control (MAC) and Physical Layer (PHY) protocols specified in the IEEE 802.11p standard, C-ITS is moving rapidly towards deployment in Europe and other regions. In the US, where the technology is known as Dedicated Short Range Communication (DSRC), the Department of Transportation has published an Advance Notice of Proposed Rulemaking with an intention to require this equipment in new cars within a few years. This is one in hundreds to sense the beginning of new chapter in the motor vehicle industry.
Currently, there are a few primary VANET channel congestion control candidates introduced by the European Telecommunication Standardization Institute (ETSI) and other corporations, as well as academic community, which are serious contenders for standardization and deployment. We believe that it is important to gain a thorough understanding of the stability and performance of these protocols by analysing them. We also took advantage of network simulators to reach a better understanding of their behavior.
