Nowadays cloud computing is very popular for offering services over the Internet. The very important advantage of cloud computing is the ability to provision resources on demand. This avoids the problems of over-provisioning and under-provisioning which are commonly seen with organizations that have widely variable requirements due to increase/decrease, seasonal high and low workload etc. Resou...

Workflow technologies have become a major vehicle for the easy and efficient development of science applications. When integrating the workflow technology with the state-of-art resource provisioning technology, the challenge is to determine the amount of resources necessary for the execution of workflow. This paper introduces an algorithm named Balanced Time Scheduling (BTS), which estimates th...

Cloud computing allow the users to efficiently and dynamically provision computing resource to meet their IT needs. Cloud Provider offers two subscription plan to the customer namely reservation and on-demand. The reservation plan is typically cheaper than on-demand plan. If the actual computing demand is known in advance reserving the resource would be straightforward. The challenge is how to ...

Low-latency IoT applications, such as autonomous vehicles, augmented/virtual reality devices, and security require high computation resources to make decisions on the fly. However, these kinds of applications cannot tolerate offloading their tasks be processed a cloud infrastructure due experienced latency. Therefore, edge computing (EC) is introduced enable low latency by moving processing clo...

Context-awareness can serve to make ubiquitous applications deployed for mobile devices adaptive, personalized, and accessible in dynamically changing environments. Unfortunately, existing approaches for the provisioning of context information in ubiquitous computing environments rarely take into consideration the resource constraints of mobile devices and the uncertain availability of sensors ...
