Sorting is among the most fundamental and well-studied problems within computer science and a core step of many algorithms. In this article, we consider the problem of constructing...
We introduce the novel concept of coprivacy or co-operative privacy to make privacy preservation attractive. A protocol is coprivate if the best option for a player to preserve her...
Abstract— Sensor networks are set to become a truly ubiquitous technology that will affect the lives of the people in their application environment. While providing the opportuni...
Recent work on anonymizing online social networks (OSNs) has looked at privacy preserving techniques for publishing a single instance of the network. However, OSNs evolve and a si...

—In the effort of reducing or eliminating per-flow state at routers, hence making QoS schedulers scalable in the core Internet, Flow Aggregation outperforms Dynamic Packet State...
To increase the lifespan of wireless sensor networks (WSN) and preserve the energy of sensors, data aggregation techniques are usually used. Aggregation can be seen as the process ...
