Problems solved by technology
[0006] Aiming at the problem that the current mobile crowdsensing incentive method cannot guarantee the quality of perceived data, the present invention proposes a mobile crowdsensing incentive method based on data quality perception, which utilizes edge servers for spatiotemporal anonymity, sends sensing tasks, and introduces data quality constraints and The reputation update mechanism uses the reverse auction model to reasonably select the winner set to minimize the total cost of the perception platform, solve the problem of participant privacy protection and malicious participant attacks, and reduce the computing pressure of the cloud server and reduce the delay

The invention provides a mobile crowd sensing excitation method based on data quality sensing. The mobile crowd sensing excitation method comprises the following steps: S1, a sensing platform issues asensing task set; S2, an edge server obtains a task issued by the sensing platform and sends the sensing task to a user; S3, a participant collects perception data and uploads the collected sensing data and bidding price to the edge server; S4, the edge server selects a winner set through a reverse auction algorithm and critical reward according to the sensing data, the bidding price and the reputation value matrix uploaded by the participant; S5, the edge server calculates the sensing deviation of each participant and sends the sensing deviation to a reputation management server; and S6, thereputation management server updates the reputation value matrix of the participant. According to the mobile crowd sensing excitation method, the user can be well stimulated to upload the sensing data honestly, and malicious users are restrained, so that the quality of the sensing data is guaranteed, and the platform cost is minimized.
Description
technical field [0001] The invention mainly relates to a multi-dimensional data mobile crowd sensing incentive method based on data quality perception, and belongs to the technical field of crowd sensing. Background technique [0002] Mobile crowd sensing requires the participation of a large number of ordinary users, but in the process of participating in the sensing, participants need to invest a certain amount of time and energy, and also need to consume their own equipment's power, traffic, storage, communication and other resources. In addition, the collection of sensing data is usually It is necessary to use built-in sensors of mobile devices, such as cameras, microphones, GPS, etc., which may easily cause users to worry about privacy leaks. Insufficient number of participants seriously limits the development of mobile crowdsensing. If there is no reasonable incentive mechanism, the enthusiasm of users to participate in the sensing task is not high, which will lead to ...
