Smart grids coulpled with effiicient demand side management (DSM) is an important step for greener cities of the future. DSM has the potential to significantly improve smart grid operations by reducing the peak to average ratio. Current DSM schemes are able to reduce peak load by as much as 30% which can translate to significant cost savings and reduction in green house emissions. But for realistic...
Due to the globalization, today's manufacturing industry has to mobilize as many as resources in order to satisfy needs of every customer. At the same time, the production resources are more often geographically distributed. In this context, the necessary shifting of intermediate products as well as the final delivery requires transportation among different manufacturing sites, warehouses, consumers,...
The ubiquity and convergence of wireless communication services have contributed to an unprecedented popularity of mobile communications. Given that wireless communication systems operate on radiofrequency waves, the electromagnetic (EM) radiation exposure they generate is also unprecedented and, hence, this could have adverse health effects on both humans and animals according to the World Health...
In this paper, we study the problem of optimizing the error generated in the allocation of processing elements to tasks, based on real-time scheduling. The makespan of the tasks to be scheduled is the same, in the computational grid. Tasks to be assigned to processing elements are randomly generated and are mapped to processors. Scheduling is done, considering real-time environment and mapping is...
I/O intensive jobs such as stage-in, stage-out or data clean-up jobs account for significant time in execution of scientific workflows. Workflow managers typically add these data management operations as supporting jobs to computational tasks with scheduling emphasis on compute jobs only. We present the integration of the Pegasus Workflow Management System with a Policy Based Data Placement Service...
A large part of power dissipation in a system is generated by I/O devices. Increasingly these devices provide power saving mechanisms, inter alia to enhance battery life. While I/O device scheduling has been studied in the past for real-time systems, the use of energy resources by these scheduling algorithms may be improved. These approaches are crafted considering a very large overhead of device...
