Abstract

The proliferation of mobile phones has led to the rise of mobile crowdsensing systems. However, many of these systems rely on the deep cloud, which can be complex and challenging to scale. To improve the performance of crowdsensing at the edge cloud, truth-discovery methods are commonly employed. These methods typically involve updating either the truth or the weight associated with a user’s task. While some edge cloud-based crowdsensing systems exist, they do not provide incentives to users based on their experience. In this report, we present a new approach to truth discovery and incentive-giving that considers both the user’s experience and the accuracy of their submitted data. Our modified truth-discovery algorithm updates both the weight and truth concurrently, with greater incentives offered to users who have completed more tasks and whose submitted data is close to the estimated truth. We have run simulations to show how well our suggested strategy works to enhance the incentive system for experienced users.

在边缘辅助移动人群感应中为移动工作者发现真相

手机的普及带动了移动人群感应系统的兴起。然而，这些系统中的许多都依赖于深度云，而深度云的复杂性和规模化具有挑战性。为了提高边缘云的人群感应性能，通常会采用发现真相的方法。这些方法通常涉及更新与用户任务相关的真相或权重。虽然存在一些基于边缘云的众感应系统，但它们并没有根据用户的经验为用户提供激励。在本报告中，我们提出了一种新的真相发现和激励方法，这种方法既考虑了用户的经验，也考虑了他们所提交数据的准确性。我们修改后的真相发现算法同时更新权重和真相，对完成任务较多、提交数据接近估计真相的用户给予更多奖励。我们进行了模拟，以显示我们建议的策略在加强对经验丰富的用户的奖励制度方面效果如何。
