Method and device for participatory sensing data acquisition

Abstract

The embodiment of the invention discloses a method and device for participatory sensing data acquisition. The method comprises the steps of calculating the probability of each sub-region, located in a predetermined region in a predetermined period of time, of each piece of user equipment in multiple pieces of user equipment by means of the historical movement information of the user equipment; determining the types of sensing data to be acquired when the user equipment is located in each sub-region based on sensing data acquisition capacity information of the user equipment; obtaining utility values, relevant to sensing data acquisition in the predetermined region, of the user equipment according to the calculated probability of each sub-region and the determined types of the sensing data. The method further comprises the step of selecting one or more pieces of user equipment for participatory sensing data acquisition based on the obtained multiple utility values of the multiple pieces of user equipment. According to the method and device for participatory sensing data acquisition, the user equipment participating in sensing data acquisition can be effectively selected, sensing data acquisition efficiency is improved, and data acquisition cost is reduced.

Description

technical field [0001] Exemplary embodiments of the present invention relate generally to collection of sensory data, and more particularly, exemplary embodiments of the present invention relate to methods and apparatus for participatory sensory data collection. Background technique [0002] With the continuous evolution and development of mobile communication technologies, current user equipment (eg, mobile terminals including smart phones) has expanded from a single voice call function to a collection of various complex multimedia applications. By virtue of the advantages brought by mobile communication technologies and their wide application, various types of sensors equipped with user equipment can be used to achieve a wide range of sensing data collection. For example, the built-in camera of the user equipment may be used as an image sensor to collect (or perceive) image information of the surrounding environment, thereby forming perception data about the image. For an...

Problems solved by technology

However, due to the different data perception capabilities of user equipment and the limited types of data that can be perceived, it is not realistic to rely on a specific user equipment to collect all types of sensing data

The straightforward way to solve this problem is to invite more user devices to participate in sensing data collection, but in most cases, in order to motivate users to join participatory sensing data collection, the operator of the central data server needs to pay a certain amount to participating users. remuneration, and more participants mean higher data collection costs and more network resource consumption
