A Variational Inequality Based Approach for Power Trading in Multi-User Relay-Assisted Systems

Abstract

To find out an optimal power allocation among users, and an optimal power pricing strategy at the Relay-assisted 5G wireless system, we propose a Variational Inequality (VI) based approach. We modeled the issues and provided an algorithm to resolve the issues, from the aspects of theoretical analysis and simulation analysis. The results indicated the VI-based solution was effective for the scenarios with both public and private budget limits.
