基于信任度的自私用户协作激励机制
Cooperation Incentive Mechanism for Selfish Users Based on Trust Degree
摘要
Abstract
In the multi-user network,selfish users refuse to provide other users with cooperation for saving their own energy and computing resources.In order to encourage selfish users to offer their resources,a cooperation incentive mechanism based on users trust degree evaluation is proposed.Relays decide whether to participate in the cooperation or not by comparing the trust value of communication users.The lower trust value of the selfish users,the more likely they will be rejected when they need cooperation.While the higher trust value of users,the more likely they will get cooperation.Simulation results demonstrate the effectiveness of the proposed scheme.The selfish users actively participate in the cooperation to increase their own trust value,and the communication quality is close to that of the cooperation with selfless relays.关键词
