This paper investigates the energy efficiency of sensing based spectrum sharing in cognitive radio network, where a secondary network can utilizes the primary network based the results of spectrum sensing. In the conventional sensing model, primary user is considered to remain active or inactive during the sensing slot. However, numerical results show that primary user could arrive at or depart from the band during the sensing slot of SU. A new three powers allocation strategy is proposed according to the effect of primary traffic. The resource allocation strategy is designed for the optimal energy-efficiency under the transmit power constraint and interference power constraint. Simulation results show that the energy efficiency of the proposed three power allocation is significantly improved compared with that of the conventional strategy.
