Distributed Energy-Efficient Power Optimization for Relay-Aided Heterogeneous Networks (Invited Paper)

Abstract—This paper presents an energy-efficient power allo-cation for relay-aided heterogeneous networks subject to coupling convex constraints, that make the problem at hand a generalized Nash equilibrium problem. The solution to the resource allocation problem is derived using a sequential penalty approach based on the advanced theory of quasi variational inequality, which allows the network to converge to its generalized Nash equilibrium in a distributed manner. The main feature of the proposed approach is its decomposability, which leads to a two-layer distributed algorithm with provable convergence. I
