2、,参与式感知通过采用设计有效的激励机制来鼓励、保障和吸引相对稳定有效的感知群体加入感知活动,从而提升感知数据质量,保障应用需求。因此,参与式感知激励机制的研究具有重要意义。本文基于感知任务的数据质量,并充分考虑用户在参与感知活动时,由于日常活动导致的感知数据质量动态变化的情况,研究了一种基于信息质量的参与式感知激励机制。主要研究内容包括:1)本文将参与式感知平台与用户构建成两阶段的斯塔克伯格博弈模型,通过求解平台和用户之间的纳什均衡,找到他们的最佳感知策略,并引入数据质量评价指标,通过考虑用户与感知任务的相关性,数据提交的时效性以及数据准确性,来反映用户的感知数据质量。2)本文在基于博弈模型的
3、基础上,研究了一种基于信息质量的参与式感知激励方法。该激励方法通过将感知任务分为多轮,在每一轮中以参与者的信誉度作为事先报酬分配指标,在每一轮任务结束后,依据该轮的信息质量来动态调整下一轮的报酬定价,从而保证了感知活动的可持续性。最后,通过案例分析的方式验证该机制的性能。3)基于本文研究的激励机制设计并实现一套参与式感知系统,该系统包含有安卓客户端,Web管理端以及服务器。本文阐述了系统中各主要模块的接口和逻辑设计,并展开说明了如何在系统中实现激励功能。最后以黑盒测试的方式证明系统能够有效运行。关键字:参与式感知;激励机制;数据质量;移动应用IAbstractWith the rapid de
