Dissemination latency is critical to the applications of cognitive radio networks, which have become an important component of current communication infrastructure. This paper investigates the distribution of dissemination latency in a cognitive radio network where licensed users (primary users) are static and cognitive radio users (secondary users) are moving under general mobility, which provides fundamental understanding of the fastest information delivery that a mobile cognitive radio network is able to accommodate. The authors show that the dissemination latency depends on the stationary spatial distribution and mobility capability a (characterizing the region that a mobile secondary user can reach) of secondary users.
