This paper presents the Adaptive Spectrum Opportunity Access (ASOA) scheme. The proposed scheme greatly improves spectrum utilization and provides improved QoS for the secondary users. The secondary data delivery time is adapted in different spectrum opportunities through ASOA scheme based on the estimated collision rates in a sophisticated way. The performance evaluations in terms of the channel utilization, channel collision, secondary data delivery and handoff rates are assessed and compared with the Maximum Idle Channel Remaining Lifetime (MICRL) schemes. The simulation results confirm the viability of the ASOA scheme in comparison with MICRL schemes.
