Vehicle-to-vehicle communications (V2V) are one of the most promising upcoming
technologies for the coverage of a wide spectrum of services both at comfort level and at the level
of road safety. While the study of such kind of communication is a complicated process, more and
more methods are developed in order to understand them in depth. Maybe one of the greatest
approaches is the study of V2V communications through geometry based stochastic channel
models. Depending on the propagation parameters and the techniques which are used, more and
more such models are developed with a fast pace.
For this purpose and within the framework of this Master Thesis, a model that extends the classic
two ring reference model was developed. After a survey into the international bibliography where
a large number of such kind of models was found , it was noticed that these were applicable only
to a kind of communication links where the transmission distance was fixed and maintained large.
Based on this assumption, an extension of this kind of reference model into a model that would
take into account the distances between the two mobile terminals, was held. In this context the
different statistical properties which, consequently, arise, are studied. The development of the
simulation models is used the sum-of-sinusoids method (SoS), which has been widely accepted by
academia and industry.
The proposed model, provides to other researchers a convenient framework and guidelines for
the study of such kind geometry based stochastic model from a different perspective as well as the
potential of studying a variety of propagation scenarios.
