As data is outsourced from social networks to data consumers, there exists a fundamental tradeoff between data utility and user privacy.

Location detection systems employ wireless sensor networks (WSNs) to approximate the physical position of events within an area of interest. WSNs consist of sensor and anchor nodes that are spatially distributed over the area of interest, and are overseen by a fusion center (FC) that collects node information. In applications such as fire or motion...

Wireless sensor networks use spatially distributed sensors (nodes) to monitor physical or environmental conditions, for example, temperature, and pressure. Applications of such networks include battlefield surveillance, environmental monitoring, industrial process monitoring and control, structure and vehicle monitoring, health monitoring and passive...
