An integrated distributed learning environment (IDLE) is proposed based on two designing frameworks: learning activities and instructional strategies. The proposed IDLE consists of four components: (1) online courseware, (2) virtual classroom, (3) instructional management, and (4) tools. In addition to system components, the installation of two types of instructional personnel is also suggested...

Many sensor network applications feature correlated traffic bursts: after a period of idle time with almost no network traffic, many nodes have to transmit large amounts of data simultaneously. One example is volcano monitoring [17], where rare eruptions trigger many nodes simultaneously to transmit seismic data traces. For such applications, a MAC protocol should exhibit a low overhead both in...

In this paper, we present a deterministic permutation flowshop scheduling problem with new objective function, the total core idle time. The interest of is related to reduce energy consumption system, taking into account that needed during processing times constant, and machines are switched off front back times. Therefore, dependent on time where in stand-by mode, i.e between jobs, named as Co...

Achieving an energy-efficiency control and simultaneously satisfying a performance guarantee have become critical issues for cloud providers. The existing work is power saving in Virtual Machine the potential performances overheads of server consolidation were evaluated. In this paper, three power-saving policies are implemented in cloud systems to mitigate server idle power. Three power-saving...
