This report is a brief survey of schemes used for characterization of application traffic. We discuss the different kinds of applications, and their QoS requirements. Measurement-based, Statistical model-based and Deterministic model-based schemes are used to characterize traffic, and we elucidate each scheme with an application. We look at self-similarity… (More)
Mobile Ad-hoc networks (MANETs) are increasingly popular with recent advancements in computer and communications technologies. A mobility-based clustering (MBC) protocol for wireless ad hoc network with mobile nodes works well in an energy constrained network environment, where a node elects itself as a cluster-head based on its residual energy and… (More)
This paper describes a technique for generating images on the screen wallpaper to show changes in information. By automatically collecting images from user-selected web sites, applying color filters to them, and positioning the filtered images on the screen background, our system provides a visible, non-intrusive way to raise awareness.
