Abstract
Most of the proposed cognitive radio sensor networks (CRSNs) are not really based on the IEEE 802.15.4. In this paper, we introduce the proposed IEEE 802.15.4 based zb-CRSN framework which can perform spectrum sensing in the inactive portion. The spectrum decision algorithm of first detected idle channel first (FDIC) and shorter idle time first (SITF) are proposed to aid in selecting available licensed channel for sensor nodes from more than one spectrum sensing results.
