【摘要】：设备到设备(device to device,D2D)通信允许邻近用户使用蜂窝网络频段直接通信,既能分流部分蜂窝数据,减轻基站负担,又能提升服务质量。但由于信息不对称,蜂窝网络不知道用户的类型参数,无法准确提供合理补偿,以激励用户参与数据分流。基于契约理论设计了一种分流补偿机制,首先设计蜂窝网络收益函数和分流用户代价函数及其二者的效用;然后基于用户类型参数服从均匀分布设计补偿机制,验证了该机制能满足个人理性和激励相容条件,分析了该机制的最优性能;最后与正比例补偿机制和完全信息补偿机制进行对比仿真,结果表明,本文设计的分流补偿机制既能保证用户愿意参与数据分流,也鼓励用户报告自身真实的类型参数,还能获得接近于完全信息补偿机制下的效用和性能。
[Abstract]:Device to device to deviceD2D) communication allows neighboring users to use cellular network frequency bands to communicate directly, which not only distributes part of cellular data, lightens the burden of base stations, but also improves the quality of service. However, due to asymmetric information, cellular networks do not know the type of user parameters, can not accurately provide reasonable compensation to encourage users to participate in data streaming. Based on the contract theory, a shunt compensation mechanism is designed. Firstly, the revenue function and the cost function of the cellular network and the utility of the two functions are designed, and then the compensation mechanism is designed based on the user type parameters. It is verified that this mechanism can satisfy individual rationality and incentive compatibility conditions, and the optimal performance of the mechanism is analyzed. Finally, the simulation results are compared with the positive proportional compensation mechanism and the complete information compensation mechanism, and the results show that, The shunt compensation mechanism designed in this paper can not only ensure that users are willing to participate in data streaming, but also encourage users to report their own true type parameters, and can also obtain the utility and performance close to the complete information compensation mechanism.
