Abstract

A channel allocation mechanism for cognitive radios (CRs) is proposed to enable maximum throughput and minimum forced termination probability for CR users (CUs) that are not capable of spectrum handover (SH). SH is an optimal collision-avoidance scheme used by CUs to evacuate from time-slots that will be used by primary users (PUs) based on time-slot assignment (TA) information obtained in advance. The proposed scheme has extensive applicability for CR-networks where SH is not possible owing to PU TA information not being obtainable in advance, which is very common. For CR-networks without SH capability, the proposed scheme enables remarkable throughput performance, equivalent to the level of when SH is used.
