This paper presents a review of privacy-preserving techniques for Wireless Sensor Networks (WSN). A lot of work has been done to enhance efficient use of power and resources in wireless sensor networks with the help of specific routing algorithms and different layers' protocols. As the popularity and uses of wireless sensor network increase, privacy of individuals is of very high demand. In this paper two main categories of privacy preserving techniques for WSN have been presented, data-oriented and context-oriented. Some interesting open challenges for future research have also been introduced. This paper should provide some fruitful help for further research in privacy preservation for WSN.
