摘　　要：为了激励蜂窝小区中的空闲用户充当D2D协作通信的中继,帮助D2D用户转发数据,提出一种利用虚拟货币的激励机制进行中继选择的方法。分析了D2D发送机与周围空闲用户之间的社会亲密度,保证中继选择的公平性。并对提供帮助的中继用户使用虚拟货币支付一定的报酬。结果表明,与随机选择方式、基于数据速率方式相比较,该方法提高了数据速率、中继的收益以及保证了中继选择的公平性。For the sake of motivating the idle users in the cell to act as the relays of the D2D cooperative communication and help the D2D users forward the data,an incentive mechanism incorporated with virtual currency for relay selection was proposed.The social closeness index between the D2D transmitter and the surrounding idle users is analyzed to ensure the fairness of the relay selection.In addition,a certain amount of compensation was paid for the relay users by virtual currency.The results manifest that the proposed algo⁃rithm improves the data rate,gains of relay,and guarantees the fairness of the relay selection,compared with the random selection algo⁃rithm and the algorithm based on data rate.
