Embodiment Construction

[0027] The method for maximizing the utility of redundant data proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0028] Please refer to figure 1 , which is a flowchart of a method for maximizing the utility of redundant data in an embodiment of the present invention, such as figure 1 As shown, the method for maximizing the utility of redundant data specifically includes the following steps:

[0029] First, execute step S1, the platform determines the task budget D, and releases the set of locations involved in the task T={t 1 ,t 2 ,...,t m};

[0030] N...

Abstract

The invention provides a redundant data utility maximization method. In the step that a platform selects a wining biding document from a biding document set and determines remuneration of a mobile phone user corresponding to each wining biding document, a credible combinatorial auction method in game theory is adopted, a task allocation method which has credibility, individual rationality, computational effectiveness and budget rationality is provided, redundant data utility is maximized, further task allocation of the platform has credibility, individual rationality, computational effectiveness and budget rationality.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for maximizing the utility of redundant data. Background technique [0002] In recent years, the number of smart phone users has increased dramatically, and a wealth of sensors are embedded in smart phones, and a large number of smart phone users can easily collect and share the perception data of the surrounding environment. Therefore, the smartphone-based crowd sensing system becomes an interesting method to collect and share the perception data of the surrounding environment. The crowd sensing system consists of a platform and smartphone users who are willing to contribute sensing data. Suppose a noise-mapping application wants to collect noise levels at some locations. Each mobile phone user will tell the platform where he is willing to measure the data and the corresponding price of the data service. The platform hires some mobile phone users to collect dat...
