摘要
提出一种基于拍卖模型的移动社交网络数据转发激励机制—AMIM。通过对一级密封价格拍卖模型进行扩展,并采用虚拟支付的交易方式,将节点间的数据转发过程抽象为拍卖交易模型。基于节点的资源状态、虚拟货币量和数据属性,给出了关于数据转发交易的买卖双方估价函数,节点依据相应的估价函数和博弈策略给出相应的报价。通过博弈分析给出了AMIM机制的纳什均衡解,数据转发请求节点将选择出价最低且低于其估价的竞拍节点为本次数据转发的服务节点,激励理性的用户节点为使其自身利益最大化而自愿参与数据转发交易。仿真实验结果表明,采用AMIM机制后,网络系统的能量消耗有所下降,数据转发成功率与效率均有明显提高。
A data forwarding incentive mechanism based on auction model in mobile social network was proposed. In this incentive mechanism, the first-price sealed auction mode was extended, the transaction mode of virtual currency payment was adopted, and the procedure of data forwarding between nodes was abstracted into the auction transaction model. Based on the node＇s resource state, the virtual currency and the data property, the evaluation function of data forwarding transaction was given, and then the node gives the corresponding price according to the evaluation function and game strategy. Through the game analysis, the Nash equilibrium solution of AMIM was found, and the lowest bidder, of which the bid price was lower than the evaluation of data forwarding request node would been selected as the service provider for this data forwarding. In this incentive mechanism, the rational mobile nodes were enforced to voluntarily participate in data forwarding cooperation to maximize their own interests. The simulation experiment shows that AMIM mechanism can effectively reduce the energy consumption and improve the success rate and efficiency of data forwarding in the whole network system.
