Wireless Protocol Design for a Cooperative Pedestrian Protection System
In the research project Ko-TAG, which is part of the research initiative Ko-FAS, cooperative sensor technology is developed and its benefit for traffic safety applications is evaluated. As a result the new sensor concept shall provide essential input data for next generation driver assistant systems. A secondary radar principle based on communication signals enables localization of objects with simultaneous data transmission. It mainly concentrates on pedestrian and other vulnerable road user (VRU) detection.
This paper describes the architectural approach of the system design, as well as the main characteristics of the physical and data link layers of the proposed wireless protocol. The protocol is designed in such a way that it can be used as an extension to IEEE802.11p/WAVE protocol. The complete protocol is modeled in OPNET network simulator.
