Secondary user selection in cooperative sensing scheduling

摘要

Cooperative spectral channel sensing techniques are applied in a cognitive radio network (CRN). Network characteristics and target parameter thresholds can be determined. An overall number of secondary users (SUs) assigned to sense a number of primary user (PU) channels can be determined. Further, it can be determined how many SUs to assign to sense each PU channel. In one aspect, SUs are allowed to access to PU channels based on spectrum opportunities determined by the cooperative spectral channel sensing techniques.
