Embodiment 1

[0056] figure 1 It is a flowchart of an embodiment of the mobility prediction-based crowd sensing user recruitment method of the present invention, such as figure 1 As shown, the group intelligence sensing user recruitment method includes:

[0057] Step 101, sending a mobile crowd sensing task, the mobile crowd sensing task including budget, target location, task start time and task end time.

[0058] Step 102, obtaining individual expectation values ​​of multiple mobile users, where the individual expectation values ​​represent the probability that the mobile users arrive at the target location on time.

[0059] The personal expectation value is sent by the mobile device of the mobile user, and the specific calculation method of the personal expectation value is:

[0060] Obtain personal spatiotemporal trajectory information of mobile users; the personal spatiotemporal trajectory information includes: points of interest, time of entering said point of interest and time of l...

Embodiment 2

[0077] Embodiment 2 provides a mobility prediction-based crowd sensing user recruitment method, which specifically includes:

[0078] (1) In the preparation stage, mobile users collect their own spatiotemporal trajectory information, and construct a personal spatiotemporal semi-Markov mobility prediction model. A spatio-temporal trajectory is a collection of multiple spatio-temporal information triples , where l represents the point of interest, ts and te represent the time of entering and leaving the point of interest. According to the set of spatio-temporal information, the first core formula of the semi-Markov model can be obtained according to statistics:

[0079]

[0080] Among them, Z u (i, j, T) represents the probability that a mobile user transfers directly from point of interest i to point of interest j within T time, S u Indicates the sequence of POIs visited by mobile users, and the access time of POIs visited by mobile users. Obviously, the next POI visited b...

Abstract

The invention discloses a mobility prediction-based crowd sensing user recruitment method and system. The method comprises the steps of sending a mobile crowd sensing task, wherein the mobile crowd sensing task comprises a budget, a target location, task starting time and task termination time; obtaining personal expectation values of multiple mobile users, wherein the personal expected values represent the probabilities of reaching the target location on time by the mobile users; according to the personal expectation values and a data uploading mode, determining success probabilities, whereinthe success probabilities represent the probabilities of successfully finishing the mobile crowd sensing task by the mobile users; determining maximum values of the success probabilities; and determining the mobile users corresponding to the maximum values of the success probabilities as recruitment objects. According to the technical scheme, the applicability of a mobile crowd sensing application and a user recruitment module are improved.

Description

technical field [0001] The present invention relates to the technical field of mobile crowd sensing, in particular to a method and system for recruiting crowd sensing users based on mobility prediction. Background technique [0002] Mobile Crowdsensing (Mobile Crowdsensing) is a new type of mobile user-centric perception and computing paradigm. Its main purpose is to use the portable devices carried by a large number of mobile people to complete large-scale perception and computing tasks. Compared with traditional fixed-deployment wireless sensor networks, mobile crowd sensing not only greatly improves the perception and observation capabilities, but also breaks through the original limitations in terms of scalability. In recent years, mobile devices represented by smartphones have developed rapidly, and various types of miniaturized sensors have been embedded in mobile devices, greatly improving the perception capabilities of mobile devices. With the explosive popularity o...
