Embodiment Construction

[0052] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0053] The present invention proposes a crowd-sensing Internet of Vehicles user screening method combining vehicle trajectory clustering and combined multi-arm gambling machine (CMAB), which is specifically implemented according to the following steps:

[0054] Step S1: Construct user trajectory clustering features for the driving trajectories of Internet of Vehicles users, and cluster users with similar trajectories into the same cluster users.

[0055] Given the road network first, divide the minimum bounding rectangle covering the entire road network into a series of grid units. A trajectory containing a vehicle's start location, trip location, and goal location is projected onto a gridded road network and represented as a time-ordered sequence of grid cells covering their locations. The distance between different trajectories is calcul...

Abstract

The invention relates to a method for screening users of the Internet of Vehicles through crowd sensing combined with clustering and CMAB. The method includes: constructing user trajectory clustering features for the driving trajectory of the Internet of Vehicles users; using the CMAB model, using the trajectory clustering information as the basis for user task assignment, and solving the best worker combination; according to the real taxi trajectory data set The method was validated by analysis. The user screening method of the present invention combines the user trajectory information with the CMAB model, overcomes the phenomenon of poor perception data quality caused by the low skill level of users participating in the perception task, and enables the selected workers to have similar driving skills Trajectory; at the same time, this method can make the task allocation algorithm based on the user screening results stabilize faster and earlier. Therefore, it is suitable for practical application scenarios.

Description

technical field [0001] The invention relates to the field of crowd-sensing Internet of Vehicles, in particular to a crowd-sensing Internet of Vehicles user screening method combined with clustering and combined multi-arm gambling machine (CMAB). Background technique [0002] With the continuous updating of embedded devices and the gradual expansion of Internet coverage, social sensing activities in smart cities have become a research hotspot in the field of information and communication. Crowd sensing technology replaces the traditional sensor network, making the sensor more real-time, convenient and low-cost, and more truly reflects the real-time status, avoiding the defects of the traditional model. In the research related to crowd perception, task allocation is one of the core issues studied by scholars at home and abroad. The research in this area is mainly divided into two categories: task independent selection and task coordination allocation. In the process of task a...
