A cooperative strategy based on Nash bargaining solution under spectral mask constraint in cooperative relay networks

Abstract

Resource allocation among multiple users interference channel has posed significant issues in cooperative communication networks. A game-theoretic approach is studied under spectral mask constraints (SMCs) in cooperative relay networks using Amplify-and-Forward as a relaying protocol. The cooperative strategy employed as game-theoretic approach is based on the Nash bargaining solution (NBS). The Nash equilibrium and Nash bargaining solutions are derived for a two-player game based on the joint time division multiplexing and frequency division multiplexing (TDM/FDM) as a mode of cooperation.The condition for the uniqueness and existence of the NBS is derived.
