Abstract :
The current spectrum allocation model aims to avoid interferences in licensed spectrum communications without further concerns regarding spectrum usage. Because the radio spectrum is a finite resource, several approaches have been presented in order to improve the effectiveness of its utilization. The main contribution of this work is to present an opportunistic approach to spectrum sensing and allocation. Compared to other alternatives, our approach presents significant improvements in the spectrum access and utilization, improving network throughput up to 16 times.
