A SURVEY ON DATA COLLECTION IN CROWDSENSING SYSTEMS

Abstract

Crowdsensing is considered as a promising data collection model in which platforms outsource sensing tasks to a large number of users. In mobile crowdsensing(MCS), citizens participate in the sensing process, contributing data with their mobile devices, such as smartphones, tablets and wearable devices. First of all, we discuss the basic concept, system architecture and application of mobile crowdsensing. Then, combined with the development status of data collection mechanism of mobile crowdsensing at home and abroad, three types of data collection mechanism are introduced in detail, including data collection mechanism based on data quality, data collection mechanism based on node coverage and data collection mechanism based on compressed sensing.Finally, the article is summarized.
