Demand-Oriented Optimal Spectrum Sensing Order in Dynamic Spectrum Access

Abstract:

In this paper, we proposed a more practical spectrum sensing order problem in cognitive radio networks (CRN), considering the effect of different traffic of second user (SU). We discard the impractical assumption that SU has data packets to transmit all the time, and use the actually packets per second rather than the channel capacity as the definition of throughput, to reformulate the optimal sensing order problem. The new method to decide sensing order can improve the throughput performance in practical system.
