Problems solved by technology

However, the existing unified price remuneration mechanism lacks fairness and incentives, and the price-based remuneration mechanism condones the careless behavior of some crowdfunding crowdfunders. Neither of these two methods can maintain long-term efficient data collection and high-quality data collection. crowdfunding service

Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] The present invention designs a mixed incentive method for group crowdfunding of indoor location information, based on the fact that each crowdfunder uploads the beacon perception data about each target location in the room, and realizes the screening of crowdfunders corresponding to each target location, In practical applications, the design specifically performs the following steps A to C.

[0033] Step A. Based on each crowdfunder x i The uploaded time-series sensing data sequences corresponding to the preset beacon sensing data types such as wireless signal strength for each target position in the room constitute each crowdfunder x i Respectively uploaded beacon perception datasets for all indoor target locations Obtain the maximum mutual information value between the beacon sensing data sets corresponding ...

Abstract

The invention relates to a mixed incentive method for group crowdfunding of indoor location information, which applies the idea of ​​crowdfunding participation, considers the difference in quality of indoor location information provided by crowdfunders, and designs and uses the correlation analysis of the largest information coefficient to filter potential malicious crowdfunders. And use the unsupervised learning algorithm of weighted clustering and ReliefF to quantify the data quality, so based on the acquisition of the sensory data of the target position beacon, the design realizes the acquisition of the label information corresponding to the target position, and realizes the logical positioning of each target position in the room, and In the application, a mixed incentive framework is introduced to encourage perception crowdfunders to provide high-quality perception data for high-quality perception services, satisfy the perception crowdfunders' personal rationality, approximately maximize the performance of the perception platform, and in terms of quality assurance and efficiency management , which has better performance than existing methods.

Description

technical field [0001] The invention relates to a mixed incentive method for group crowdfunding of indoor location information, which belongs to the technical field of wireless communication. Background technique [0002] Indoor positioning services have attracted much attention in recent years due to their social and commercial value, and indoor positioning technology based on WiFi fingerprints has become popular due to its minimal hardware requirements and relatively good positioning accuracy. In indoor positioning based on WiFi fingerprints, positioning is divided into an offline training phase and an online positioning phase. Among them, the offline training phase mainly allows some professionals to collect WiFi at each location by conducting on-site surveys in the positioning area. Fingerprint data, and then build a fingerprint database. In the online positioning stage, the system will match the WiFi fingerprint of the user's location with the fingerprint of the finger...
