针对蜂窝网络控制下的终端直通(D2D)通信中的数据转发问题,提出了一种基于合同理论的D2D数据协作转发机制。首先,充分考虑用户的自私特征,构建了一种以D2D发送用户为合同委托方、以空闲用户为代理方的委托—代理模型。然后,利用合同双方的效用函数以及合同约束条件构建含约束条件的优化问题,并且将合同双方的效用函数转化为合同双方满意度,最后构建为最小权重的稳定匹配,从而获得最优合同解。仿真结果表明,所提出的算法能够较好地激励空闲用户参与协作通信,进而提升用户满意度以及吞吐量。
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.
