A Review on PEPSI Architecture

The extreme use of mobile phones has magnified the quantity of digital knowledge created and processed on a daily basis. Participatory Sensing (PS) is associated paradigm that focuses on the collection of digital knowledge created from an oversized variety of connected, always-on, always-carried mobile devices. PS takes the advantage of fast movement of the sensor-equipped devices and therefore the omnipresence of broadband network infrastructure produces sensing applications wherever readying of a WSN infrastructure is not economical or impractical. It targets to provide high level of privacy and security in participatory sensing to knowledge producers like users. They focus on privacy protection in Participatory Sensing and introduce a suitable privacy-enhanced infrastructure.
