Parameter adaptation in green cognitive radio
Zheng Shi-Lian, Yang Xiao-Niu · Acta Physica Sinica · 2012
The model for parameter adaptation problem in green cognitive radio and a particle swarm optimization based solution are proposed. Simulations are conducted to show the performance of the proposed method. Results show that given different quality of service (QoS) requirements, the proposed method can reduce the total transmit power of the system while maintaining the QoS requirements. Thus the goal of reducing energy consumption is reached.
