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 correspondin...

Abstract

The invention relates to a hybrid excitation method for indoor position information group crowdfunding, which applies a crowdfunding participation thought, considers indoor position information quality difference provided by crowdfunders, and designs correlation analysis adopting a maximum information coefficient to filter potential malicious crowdfunders, and adopts a weighted clustering and ReliefF fused unsupervised learning algorithm to quantize the data quality, so that based on the acquisition of target position beacon sensing data, the acquisition of mark information corresponding to a target position is designed and realized, the logic positioning of each indoor target position is realized, and in the application, a hybrid excitation framework is introduced, the perceptual crowdfunders are stimulated to provide high-quality perceptual data for high-quality perceptual services, the personal rationality of the perceptual crowdfunders is met, the perceptual platform efficiency is approximately maximized, and compared with an existing method, the method has better performance in the aspects of quality guarantee and efficiency management.

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...
