A Survey on Participatory Sensing Systems

Asha Raj, Abeera V P

Abstract: Wireless networks consist of a collection of large number of sensor nodes. The emergence of various sensors made the emergence of participatory sensing systems. Sensor data, in its original form, contains sensitive information about individuals. Privacy protection is very important for participatory sensing systems. In wireless networks, the nodes communicate with each other through wireless medium. Data aggregation helps in reducing the number of bits transmitted thereby reduces the total energy consumption. In this survey, we summarize different privacy preserving techniques and data aggregation protocols for wireless sensor networks. We also provide a brief description of Reed-Solomon erasure coding technique to detect and correct errors in transmission.

Keywords: Participatory sensing, privacy preserving, collaborative path hiding, data aggregation, erasure coding
