Abstract:The spectrum access strategy is one of the important design aspects for better system capacity in cognitive radio networks (CRN), which is characterized as complex and concurrent access processing of multiple users. The common approach modeling spectrum access is Markov Chain (MC), which is prone to state space explosion with the increasing of the number of users. In this paper, an executable hierarchical Colored Petri Nets (CPN) model for the spectrum access in CRN is investigated to overcome the explicit lim… Show more
