Abstract—Impulse Radio Ultra-wideband (IR-UWB) communication has proven an important technique for supporting highrate, short-range, low-power communication. These are necessary ...
Low-cost and low-power video surveillance systems based on networks of wireless video sensors will enter soon the marketplace with the promise of flexibility, quick deployment an...
We consider coverage problems in sensor networks of stationary nodes with minimal geometric data. In particular, there are no coordinates and no localization of nodes. We introduc...
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...
Wireless Sensor Networks (WSNs) are challenging types of networks where resources can be scarce. In particular, battery is often a very limited resource and the radio interface is...
