In this master thesis, a performance analysis of an information-theoretic location verification system using directional antennas is performed, considering a vehicular network scenario. Our goal is to develop a method using directional antennas to improve the system performance. First, a recently introduced scheme that uses a simple propagation model is studied, then it is described the modifications needed when a realistic propagation model is considered. Based on the described scheme, it is shown how the use of directional antennas can be introduced into the system, creating a new validation stage called directional verification. Numerical results are used to validate the analytical expressions, showing also the performance differences between the described systems. Using the obtained results, it is shown that the use of directional antennas increase the system performance and that, even when using only the directional verification stage, the performance is satisfactory. An analysis of the relation between the number of samples and the system's error percentage is also performed, when considered a small scale fading model. |
