Channel Efficiency of Adaptive Transmission Techniques for Wireless Vehicular Communications

The adoption of wireless vehicular communication technologies would strongly depend on the technologies transmission reliability, required by QoS demanding traffic safety applications, and the system's scalability as the technology is gradually introduced. To this aim, this paper proposes the use of opportunistic transmission policies that dynamically adapt the transmission parameters based on the operating conditions and potential traffic safety risks. The paper shows that this proposal adequately meet the strong traffic safety QoS requirements while ensuring an efficient system level channel use, crucial to guarantee the future system's scalability.
