A dynamic spectrum access MAC protocol based on spectrum analysis and spectrum sharing

The radio spectrum is a finite resource and the current spectrum licensing model has led to a fenomenon known as spectrum scarcity. Several approaches have been presented in order to improve the effectiveness of spectrum utilization. This works main contribution is is to present an approach to opportunistic spectrum sensing and allocation focused on maximizing spectrum usage while minimizing communication time and interference on primary communications. Compared an alternative, our approach presents significant improvements in the spectrum access and utilization, improving network throughput up to 16 times.
