Extensive research in recent years has shown the benefits of cognitive radio technologies to improve the flexibility and efficiency of spectrum utilization. This new communication paradigm, however, requires a welldesigned spectrum allocation mechanism.

The auction outcome when all bidders follow the proposed strategies was compared with the efficient outcome of the au...
