With the ease of deployment, capabilities evading jammers and obscuring their existence, unmanned aerial vehicles (UAVs) are one most suitable candidates to perform surveillance. There exists a body literature in which inspectors follow deterministic trajectory conduct surveillance, results predictable environment for malicious entities. Thus, introducing randomness surveillance is particular i...

In this paper we study the problem of energy-aware resource allocation for hosting long-term services or on-demand compute jobs in clusters, e.g., deployed as part of computing infrastructures. We formalize the problem as three constrained optimization problems: maximize job performance under power consumption constraints, minimize power consumption under job performance constraints, and optimi...

The concept of energy aware software is introduced. A simple energy model for software is presented that separates the switching and leakage components and predicts its total energy consumption with less than 5% error for a set of benchmark programs. The experiments have been performed on the StrongARM SA-1100 microprocessor. A mathematical model for the total leakage current has also been prop...

To tackle the application management, we use the TUNe middleware which is an autonomous management system for distributed application, using schemas that act on reaction of events. As current version does not take into account energy, we use TUNe as a basic tool and we add generic schemas to reduce energy consumption of application by using an energy-aware placement algorithm which takes into a...

Energy is swiftly becoming a gating issue in large scale storage systems, from high-performance computing (HPC) to data intensive applications. For example, the Square Kilometre Array (SKA) [3] is a large radio telescope array expected to be finished by 2024. Its dishes will produce about one exabyte (EB) of raw image data per day. However, the power envelope goal for the storage systems of fut...

We present a design technique for colors with the purpose of lowering the energy consumption of the display device. Our approach is based on a screen space variant energy model. The result of our design is a set of distinguishable iso-lightness colors guided by perceptual principles. We present two variations of our approach. One is based on a set of discrete user-named (categorical) colors, wh...
