Clock skew is defined as the rate of deviation of a device clock from the true time. The frequency of a device's clock actually depends on its environment, such as the tempera...
Abstract— Sensor networks are being increasingly deployed for collecting critical data in various applications. Once deployed, a sensor network may experience faults at the indiv...

We consider the problem of selecting a subset of p out of n sensors for the purpose of event detection, in a wireless sensor network (WSN). Occurrence or not of the event of intere...
Recent development of Wireless Sensor Networks (WSN) has led to the appearance of many application specific communication protocols which must be energy-efficient. Among those pro...
—In wireless sensor networks, multiple-coverage, in which each point is covered by more than one sensor, is often required to improve detection quality and achieve high fault tol...
