DSA-based V2I communication under the microscope

This paper presents a consice yet comprehensive description of a DSA-based Vehicle-to-Infrastructure (V2I) communication system operating under spectral scarcity conditions. Existing mathematical models for such a system overlook some but essential ones of its behavioural characteristics. Thus, these models´ reported performance results seem to be unrealistically overoptimistic. In this paper, a simulation study is conducted in the context of a real-life scenario. As opposed to the existing studies, the study herein aims at providing more insights into the dynamics of this type of communication systems and assessing its performance in terms of several new metrics.
