— This paper proposes few ways of improving a WSN’s energy efficiency that already uses an energy efficient data routing protocol for continuous monitoring application. The p...
Motivated by many applications, top-k query is a fundamental operation in modern database systems. Technological advances have enabled the deployment of large-scale sensor networks...
Wireless sensor networks are widely adopted in many location-sensitive applications including disaster management, environmental monitoring, military applications where the precise...
In sensor networks, continuous query is commonly used for collecting periodical data from the objects under monitoring. This sort of queries needs to be carefully designed, in orde...
—In a wireless sensor network, an adversary equipped monitoring antenna can easily overhear packets, which may facilitate identifying the directions of packet flows and trace to ...
