To increase the lifetime of the sensor networks, a recognized method is to switch off/on some sensor nodes between “sleep” and “activity” mode in order to save the energy....
—In this paper, an anti-sensor network system is proposed, aiming to protect an important area from being under surveillance by an adversary’s sensor nodes. The major component...
Scalable energy-efficient training protocols are proposed for massively-deployed sensor networks, where sensors are initially anonymous and unaware of their location. The protocol...

Event detection and tracking are attractive research issues in the wireless sensor network (WSN). The paper proposes a fully distributed protocol, CollECT, to event detection and ...
Abstract. Due to their small form factor and modest energy budget, individual sensors are not expected to be GPS-enabled. Moreover, in most applications, exact geographic location ...
