时空众包任务分配研究综述

Spatial crowdsourcing is a new type of crowdsourcing computing model. The core problem is how to assign the crowdsourcing tasks with spatial characteristics to the crowdsourcing workers who meet the spatio-temporal constraints. Nowadays, there are many researches on spatial crowdsourcing task assignment from different perspectives, which need to be summarized. This paper will provide a survey of spatial crowdsourcing task assignment. Firstly, the background, application fields and spatial crowdsourcing system are introduced. Then, relevant researches are classified and the optimization goals, application scenarios and algorithm implementation of existing researches are discussed. Finally, the problems of spatial crowdsourcing task assignment are summarized.
