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

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.
