Wireless sensor network (WSN) has been widely used in information collection and monitoring applications. At the center of attention in these applications are data, which come from the sensor part of each WSN node. Sensor faults are common due to the sensor device itself and the harsh deployment environment. These faults may degrade the data quality from the very beginning and thus have a possible...
Event detection has always been an important application in the practical deployment of wireless sensor networks (WSNs). Although threshold based event detection method works well in some cases when significant characteristics exist for specific event, it has some limitations in many other application scenarios when we do not know much priori knowledge on incoming event. Inspired by the latest development...
Location information is always useful in wireless sensor networks (WSN). The precision of localization is crucial for some specific applications. Methods for node localization in WSN usually rely on the measurements of received strength or time-of-flight of an incoming signal. The quality of these measurements always has great influence on the precision of localization. In this paper, special emphasis...
