摘要:

群智感知是一种有前景的感知范式,其主要借助大量移动设备中的多样嵌入式传感器来完成数据感知任务。群智感知中的一个关键问题是如何有效地协调移动设备用户同时执行多项感知任务。通过在感知任务和用户之间引入一个新的数据层,从而有效地利用感知任务的相似性和用户的异质性,在数据层之上建立联合任务选择和用户调度问题,旨在最大化整个系统的社会福利。这个问题因其组合特性以及存在感知任务和用户两方面的私有信息而很难解决。为了处理上述问题,提出了一种双边随机拍卖机制,并证明其能够满足计算高效性、个体理性和期望意义下的激励相容性。仿真结果表明,所提的随机拍卖机制可以接近最优的社会福利,并且数据复用带来的社会福利收益会随着任务相似性的增强而显著增加。

Abstract:

Crowd sensing is a promising sensing paradigm,which mainly uses a variety of embedded sensors in a large number of mobile devices to accomplish data sensing tasks.One of the key issues in crowd sensing is how to effectively coordinate mobile device users to perform multiple sensory tasks simultaneously.By introducing a new data layer between the sensing task and the user,the similarity of the sensing task and the heterogeneity of the user were effectively utilized,and the joint task selection and user scheduling problems were established on the data layer,aiming at maximizing the social welfare of the whole system.This problem was difficult to solve due to its combinatorial nature and the presence of private information on both the sensing tasks and the users.In order to deal with these problems,a two-sided randomized auction mechanism was proposed,and it was proved that it can satisfy the desirable properties of the computational efficiency,the individual rationality,and the incentive compatibility in expectation.The simulation results show that the proposed stochastic auction mechanism can achieve nearly optimal social welfare,and the social welfare benefits brought by data reuse will increase significantly with the enhancement of task similarity.

Key words: crowd sensing, data reuse, incentive mechanism, auction mechanism
