Advances in the sensing capabilities of smartphones have resulted in the emergence of crowdsensing. In a crowdsensing campaign, ordinary citizens are recruited to collect sensor data from nearby environments which are then analysed to provide useful information. In order for a crowdsensing application to be a success, sufficient number of well-suited participants should be recruited to contribute. In this paper, we make a review on the works presented to address the challenge of participant recruitment in crowdsensing systems. We first have a short review on the related works in the area of online communities and crowdsourcing systems. Then, we present a review of the works specifically related to crowdsensing systems.
