Obstacles of Mobile Crowdsourcing: A Survey

Mobile Crowdsourcing is now a highly compelling topic for research. Using crowdsourcing, a user can request for a solution to any problem he or she is facing to the mass people. In today’s world, crowdsourcing can be applied to solve industrial, academical, business, and other problems. The utility of the crowdsourcing system depends on the involvement of the people in the task. However, due to several reasons, people become unwilling to participate in crowdsourcing tasks. In this paper, we have identified the reasons that prevent users from engaging in the crowdsourcing task. The obstacles are later classified according to the types of participants of a crowdsourcing task. Each of the participants has several obstacles that demotivate them from participating in the crowdsourcing. This survey paper will support us to understand the challenges that should be faced when designing a crowdsourced framework. If we can address these challenges, it will be easier to build a crowdsourcing framework to solve any problem.
