In order to extent the lifetime of cognitive radio network based on clustered architecture
the role of cluster head need be changed for balance the energy consumption in cognitive radio network.A energy consumption model is proposed to describe the different between the cluster head nodes and common nodes
and then DTACRA (Double Thresholds Adaptive Cluster Rotation Algorithm) is presented
which double rotation energy thresholds are estimated using cluster head real-time energy load.The simulation results show that comparing with LEACH and EDAC
DTACRA maximizes the utilization of the nodes energy and prolongs the network lifetime.
