Mobile crowd sensing : task assignment, privacy protection, incentive, and application

Mobile crowd sensing(MCS) system takes mobile intelligent devices (smart phones, tablets, etc.) carried by ordinary users as the basic perception unit. Through the mobile Internet (Wi-Fi, cellular network and wired network, etc.), conscious or unconscious collaboration is carried out to realize the distribution of sensing tasks and the collection and analysis of sensing data. Able to perform large-scale, complex perceptual tasks. The task completion of the mobile swarm intelligence sensing system depends on the participants or mobile intelligent devices, which leads to the need for the mobile swarm intelligence sensing system to meet certain constraints. In view of this, we described the task assignment model, privacy protection mechanism, incentive mechanism and other contents of the current mobile swarm intelligence perception system, and discussed the various applications of mobile swarm intelligence perception in life. Finally, the research direction of mobile swarm intelligence sensing system is proposed to improve the performance of mobile swarm intelligence sensing system in the future.
