Resumen
Vehicular collision avoidance systems can improve road safety by means of periodic exchange of status information between neighbouring vehicles. At urban intersections, the
effect of shadowing caused by buildings has
a severe impact on the communication links,
leading to a connectivity performance degradation due to attenuation of the radio signal. A solution to the shadowing problem is
to use vehicles or dedicated Road-Side Units
(RSUs) as relay nodes, in urban intersections
obstructed by buildings. In this paper, we
analyze how an RSU improves connectivity
in scenarios where vehicles are approaching
over perpendicular roads on an intersection
with obstructing buildings. We evaluate the
connectivity provided by the system in terms
of the notification position, number of beacons received, and link life time. The simulation results show that using an RSU in
this scenario significantly improves connectivity, hence, providing better conditions for the
operation of road safety-oriented applications.
