Resource Allocation in a NOMA-Based VWN

In this chapter, we consider the resource allocation problem in a NOMA-based VWN. Specifically, we formulate a power-efficient resource allocation problem in a NOMA-based VWN to find the optimal power allocation coefficients to users while maintaining the slice isolation requirements. By using various convexification approaches, we develop a computationally efficient algorithm that tries to minimize the total transmit power from the BS. The simulation results performed demonstrate that the proposed NOMA scheme significantly outperforms the OFDMA scheme in terms of the power efficiency.
