摘要：

针对群智感知中的平台在用户稀疏区域获取的任务数据可靠性低且任务难以按时完成的问题，提出一种联合区域热度和社交属性感知的参与者选择机制。首先，考虑不同区域热度对任务完成程度的影响，根据区域活跃用户数、用户平均停留时间及区域历史感知任务完成情况评估区域热度。其次，为了分析用户社交属性对任务完成程度的影响，结合用户的状态信息和用户历史感知任务记录计算用户意愿度、信誉度以及活跃度；综合考虑上述因素，分别为高热度和低热度区域设计了以最大化任务完成质量和最大化任务完成数量两种不同的社交属性感知的参与者选择机制。结果表明，所提机制能够显著提升总体数据质量，在低热度区域也可以及时可靠地完成感知任务。相比于SUR和GGA-I两种算法，失败率分别降低了66.7%和50.6%。

Abstract:

Aiming at the problem of tasks that are low reliability acquired by platform and difficult to accomplish on time in user sparse area.A participant selection mechanism that combines regional heat and social attribute aware was proposed.Firstly,considering the influence of different regional heat on task completion,the regional heat was evaluated according to the number of active users,the average residence time of users and the completion of historical task.Secondly,in order to analyze the impact of user social attributes on task completion,the user willingness,reputation and activity were calculated by combining the status information of users and the historical task record of users.Finally,by taking the above factors into account,two different mechanisms of participant selection for social attribute perception were designed for high and low heat areas to maximize quality and number oftask completionrespectively.The results show that the proposed mechanism can significantly improve the overall data quality,and can also perform sensing tasks in sparse areas on time.Meanwhile,compared with SUR and GGA-I,the failure rate is reduced by 66.7% and 50.6% respectively.
