Smart grids propose new solutions for electricity consumers as a means to help them use energy in an efficient way. In this paper, we consider the demand-side management issue that exists for a group of consumers (houses) that are equipped with renewable energy (wind turbines) and storage units (battery), and we try to find the optimal scheduling for their home appliances, in order to reduce th...

(2012), http://dx.doi.org/ On-line energy-efficient real-time task scheduling for a heterogeneous dual-core system-on-a-chip is a challenging problem due to precedence constraints and the varied properties of the general-purpose processor core and the synergistic processor core. This study proposes an on-line heteroge...

This article develops a comprehensive model for optimal data retrieval using multi-mode wireless sensors in a network setting. The proposed maximum data retrieval (MDR) problem jointly optimizes routing and scheduling decisions over time subject to spatial reuse and sensor resource (energy and storage) constraints. Optimal solutions to sample cases of the NP-Hard MDR problem leads to closed for...
