Executive Summary

Wireless vehicular communication systems require the design and implementation of robust and efficient communication policies to provide the strict quality of service needed by traffic safety applications while guaranteeing the system's scalability. To efficiently guarantee such requirements, the authors have developed an opportunistic-driven adaptive radio resource management mechanism that adapts the transmission parameters based on the operating conditions and traffic safety requirements. Since the performance of adaptive communication techniques can be importantly influenced by channel correlation, this paper proposes several compensation policies that allow the proposed opportunistic mechanism to efficiently meet the traffic safety quality of service requirements even under correlated radio channels.
