Trust Evaluation for Participatory Sensing
Participatory sensing, combining the power of crowd and the ubiquitously available smart phones, plays an important role to sense the urban environment and develop many exciting smart city applications to improve the quality of life and enable sustainability. The knowledge of the participatory sensing participants’ competence to collect data is vital for any effective urban data collection campaign and the success of these applications. In this paper, we present a methodology to compute the trustworthiness of the participatory sensing participants as the belief on their competence to collect high quality data. In our experiments, we evaluate trust on the sensing participants of BusWatch, a participatory sensing based bus arrival time prediction application. Our results show that our system effectively computes the sensing participants’ trustworthiness as the belief on their competence to collect high quality data and detect their dynamically varying sensing behavior.
