DSRC, its Future and the Project
Cooperative Intelligent Transport System (C-ITS) technology enables a wide variety of vehicular ad hoc networking applications, including Forward Collision Warning (FCW), Road Hazard Awareness, and Route Guidance. 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. Currently, there are a few primary V2V channel congestion control candidates introduced by the European Telecommunication Standardization Institute (ETSI), as well as the academic community, which are serious contenders for standardization and deployment. This project aims to gain a thorough understanding of the stability and performance of these protocols.
Summary of the project:
- Designed, implemented and validated the European Decentralized Congestion Control (DCC) Mechanism in Network Simulator 2 (ns-2).
- Implemented and validated Cooperative Awareness Message (CAM) generation algorithm.
- Evaluated the European DCC in terms of stability of the algorithm and further compared it with LIMERIC – a candidate congestion control algorithms for deploying across the United States.
- Analyzed the channel load instability caused by the European DCC and provided alternative stable designs.
