基于机会协作传输的群智感知网络激励机制

摘要

移动群智感知网络中用户激励机制是研究的重点,而如何有效减少用户在任务中移动设备资源的消耗是激励用户的关键.根据群智感知用户分布密集和相遇频繁的特点,利用其移动设备的短距离无线通信能力(蓝牙、Wi-Fi)进行数据的机会协作传输将极大减少用户消耗,进而激励用户完成任务.通过对机会传输和群智感知激励机制的研究,针对ecoSense机制[9]在补偿方案、预算控制和用户激励方面的不足,提出C-ecoSense 机制降低任务总预算,并通过POR和PIM激励机制激励用户上传完成任务.最后采用SWIM仿真数据集进行实验.结果表明与普遍使用的数据收集机制相比,C-ecoSense机制在预算控制和用户激励方面都具有更好的效果.%Incentive mechanism is the key point of research in mobile crowd sensing, and how to effectively reduce the consumption of mobile device resources in the task is the key to motivate users.According to the characteristics of crowd sensing that users were densely distributed and meet frequently, the short distance wireless communication capability of mobile devices(Bluetooth, Wi-Fi)could be used to transmit data by opportunistic cooperative transmission,which greatly reduced user consumption and encourage users to complete tasks.Through the research on opportunistic networks and crowd sensing incentive mechanism,the C-ecoSense mechanism was proposed to reduce the total budget of tasks according to the lack of ecoSense [9]mechanism in refund plan,budget control and user incent and motivated users to upload and complete tasks through POR and PIM incentive mechanisms.Finally, experiments were used SWIM simulation datasets.The results showed that the C-ecoSense mechanism had better performance in terms of budget control and user incentive than the commonly used data collection mechanism.
