Participatory sensing is an approach to data collection that offers individuals and groups the opportunity to participate in an application using their sensor devices. Receiving contributions from multiple individuals may result however, in corrupted and inaccurate sensed data. Therefore, it becomes important to be able to have enough knowledge about each participant in order to evaluate their contributions and trustworthiness. In this paper, we present a Reputation System to Evaluate Participants (RSEP). The RSEP, starts with grouping participants based on their contributions, and then selects the highest group value based on its participant reputation values. The RSEP filters the sensed data to separate out the most accurate contributions that enhance the purpose of the participatory sensing applications. Experimental results show that the proposed RSEP has a high accuracy level in evaluating and selecting participant contributions.
