Joint utility optimization algorithm for secure hybrid spectrum sharing
文献摘要：
As the rapid development of wireless communication networks has resulted in better user experi- ences , the spectrum resources occupied and energy consumption have increased considerably and re- sulted in great costs. To address the energy consumption and cost problems of spectrum sharing in cognitive radio networks, a hybrid spectrum sharing model combining the free spectrum of authorized users and the leased spectrum of mobile network operators is given. Based on the hybrid model, a function of throughput and costs, including energy consumption and transaction costs, is construc- ted, and a joint utility optimization problem is analyzed. The transactions between secondary users and primary users are performed on the consortium blockchain on which users can directly trade spectrum and the transaction information is recorded. In order to improve the joint utility, the La- grange multiplier method is used to achieve the optimal solution for the sensing time, the number of secondary users involved in sensing, and the transmission power. The simulation results show that the joint utility optimization algorithm proposed in this paper can achieve higher joint utility under the constraints of the minimum throughput requirement and maximum transmission power.
