In ZigBee cluster-tree network, the existing literature works does not provide solution for power efficient scheduling. In addition, the technique to prevent network collision is not explained. In order to overcome these issues, in this paper, we propose Energy Efficient Cluster scheduling for IEEE 802.15.4 Cluster-Tree Network. In this technique, initially, the distributed Pull-Push-Relabel (P...

This work presents a multi-objective approach for scheduling energy consumption in data centers considering traditional and green energy data sources. This problem is addressed as a whole by simultaneously scheduling the state of the servers and the cooling devices, and by scheduling the workload of the data center, which is comprised of a set of independent tasks with due dates. Its goal is to...

Abstract—Wireless sensor networks can be tiny, low cost, intelligent sensors connected with advanced communication systems. WSNs have pulled in significant consideration as a matter of fact that, industrial as well as medical solicitations employ these in monitoring targets, conservational observation, obstacle exposure, movement regulator etc. In these applications, sensor hubs are thickly sen...

The need for robust power-performance has enabled designers to make right direction in designing and developing the energy efficient scheduling techniques, as there is a strong need of scheduling algorithms which lowers the energy consumption and yet attain good schedules. Over the years, there has been a lot of research in scheduling the tasks for minimal schedule length and low time complexit...

Wireless sensor networks (WSNs) comprise a number of autonomous sensors and one or more sinks to cooperatively monitor physical or environmental conditions. Energy efficiency is a key design factor of a MAC protocol for WSNs. Due to the importance of the problem, a number of energy efficient MAC protocols have been developed for WSNs. Preamble-sampling based MAC protocols (e.g., B-MAC and X-MAC...

While previous work on energy-efficient algorithms focused on assumption that tasks can be assigned to any processor, we initially study the problem of task scheduling on restricted parallel processors. The objective is to minimize the overall energy consumption while speed scaling (SS) method is used to reduce energy consumption under the execution time constraint (Makespan Cmax). In this work...

Developing energy-efficient clusters not only can reduce power electricity cost but also can improve system reliability. Existing scheduling strategies developed for energy-efficient clusters conserve energy at the cost of performance. The performance problem becomes especially apparent when cluster computing systems are heavily loaded. To address this issue, we propose in this paper a novel sc...

High performance clusters play a vital role nowadays both in the industry and research area. In the past decade, some scheduling schemes have been investigated to achieve high availability or energy efficiency in large-scale clusters. However, leveraging scheduling algorithms to ensure high availability and performance while conserving energy remains an open problem. To bridge this technology g...

A mobile device may run energy consuming multimedia applications, such as video streaming. Thus, power management is an important issue in mobile devices. In this paper, we propose a QoS-guaranteed energy-efficient packet scheduling algorithm for IEEE 802.16-2009 (WiMax) network interfaces. The integration of packet scheduling and sleep mode operation can make IEEE 802.16-2009-enabled mobile de...

Scheduling the active and idle period of machine type communication devices (MTC) such as RFID tags, sensors and smart meters are significantly important to achieve energy efficiency in the emerging machine to machine (M2M) communication networks, which comprises thousands of resource constrained MTC devices (i.e., low data rate, energy and bandwidth). However, only a few studies exist in the l...
