    Abstract

    This work evaluates the secondary users’ (SUs) transmission capability considering that the primary users (PUs) can move to different positions. The transmission capability identifies the available opportunities for SU’s transmission. No opportunities are available when mobile PUs are active within the SU’s sensing region. We also consider the scenario when the PUs are undesirable detected active when they are not located within the SUs’ sensing region. Our analysis indicate that the transmission capability increases as the average mobility of the PUs decreases, which is confirmed by simulation.
