Cost-Efficient Routing with Controlled Node Mobility in Sensor Networks
In this paper, an energy-efficient strategy is proposed for tracking a moving target in a mobile sensor network. The energy expenditure of the sensors in the network is assumed to be due to communication, sensing and movement. First, the target area is

Smart Clocks Have a Hand in the Smart Grid
Clock synchronization is becoming an increasingly important characteristic of modern wide area monitoring and control systems such as the power grid. It provides an opportunity to coordinate control actions and measurement instants across hundreds of miles
Vetting Mobile Apps
Billions of copies of apps for mobile devices have been purchased in recent years. With this growth, however, comes an increase in the spread of potentially dangerous security vulnerabilities. Because of an app's low cost and high proliferation, the threat
A public randomness service
We argue for the deployment of sources of randomness on the Internet for promoting and enhancing electronic commerce. We describe, in rough detail, our planned implementation of such a source.
Predicting Failure in Complex Systems by Perturbing Markov Chain Models
In recent years, substantial research has been devoted to monitoring and predicting performance degradations in real-world complex systems within large entities such as nuclear power plants, electrical grids, and distributed computing systems. Special
O2 A-band line parameters to support atmospheric remote sensing. Part II: The rare isotopologues
Frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) was employed to measure over 100 transitions in the R-branch of the b1Σg+←X3Σg-(0,0) band for the rare O2 isotopologues. The use of 17O- and 18O-enriched mixtures allowed for line positions to be
