一种具有合谋Agent的群体感知激励机制

An Incentive Mechanism for Crowd Sensing with Colluding Agents

Susu Xu, Weiguang Mao, Yue Cao, Hae Young Noh, Nihar B. Shah

摘要:

车辆移动人群感知是一种快速发展的范例,通过在出租车等车辆上安装传感器来收集有关环境的数据。车辆人群感知中的一个重要问题是设计支付机制来激励驾驶员(代理)收集数据,总体目标是在给定预算的情况下获得最大量的数据(跨多辆车)。过去的作品在这个问题上考虑的设置,每个代理人在隔离操作-这是在实践中经常违反的假设。在本文中,我们设计了一个激励机制,以激励代理人谁可以从事任意合谋。然后,我们表明,在一个“同质”的设置,我们的机制是最佳的,可以做任何机制,知道代理人的偏好先验。此外,如果代理人是非共谋的,那么我们的机制自动地做得和任何其他非共谋机制一样好。我们还表明,我们提出的机制具有较强的(渐近最优)保证更一般的“异构”设置。基于合成数据和真实数据的实验表明,与过去的文献相比,我们的机制获得了超过30%的收益。

英文摘要:

Vehicular mobile crowd sensing is a fast-emerging paradigm to collect data about the environment by mounting sensors on vehicles such as taxis. An important problem in vehicular crowd sensing is to design payment mechanisms to incentivize drivers (agents) to collect data, with the overall goal of obtaining the maximum amount of data (across multiple vehicles) for a given budget. Past works on this problem consider a setting where each agent operates in isolation---an assumption which is frequently violated in practice. In this paper, we design an incentive mechanism to incentivize agents who can engage in arbitrary collusions. We then show that in a "homogeneous" setting, our mechanism is optimal, and can do as well as any mechanism which knows the agents' preferences a priori. Moreover, if the agents are non-colluding, then our mechanism automatically does as well as any other non-colluding mechanism. We also show that our proposed mechanism has strong (and asymptotically optimal) guarantees for a more general "heterogeneous" setting. Experiments based on synthesized data and real-world data reveal gains of over 30\% attained by our mechanism compared to past literature.
