Energy-Efficient Resource Allocation for Backscatter-Assisted Wireless Powered Communication Networks in Twin Workshop

Algorithm 3

The overall algorithm of link EE fairness resource allocation scheme.

1: Given any greater than zero, use Algorithm 2 to obtain an optimal solution to the optimization problem (14)

2: Update by bringing the optimal solution obtained in the first step into the objective function of the optimization problem (9)

3: If does not converge, let and repeat the first step; if not, let , and the solution obtained in the first step is the solution to the original problem (9)
