| Summary: | A contract theory-based D2D data forwarding mechanism was proposed for device-to-device (D2D) communications under cellular networks.Firstly,considering the selfishness of users,a model of principal-agent was constructed,which regarded the transmitter user as principal and the idle user as agent.Then,the utility function of the contract was used to construct the optimization problem with the constraint condition.Meanwhile,the utility function of the two sides was converted into the satisfaction degree of the two sides of the contract.Finally,the stable matching with the minimum weight was constructed to obtain the optimal contract solution.The simulation results show that the proposed mechanism can better encourage the idle user to participate in collaborative communication so as to enhance the user’s degree of satisfaction and throughput. |
