One significant challenge for the resource allocation in cloud environments is the pricing issue and selection of applicants of cloud resources on the basis of cloud economic parameters. Taking into account the fact that the resource allocation in cloud environments is an economic supply- and demand-based problem, economics-based methods result in better(More)
Advance reservation mechanism was introduced in grid environments to provide time quality of service requirements for time critical applications. Also there are applications that need resource coordination namely co-allocation and workflow, which benefits from this capability. Contemporary trend in grid computing is toward flexibility, because of its(More)
Task scheduling problem in cloud computing has become an active research topic due to the tremendous growth in the use of cloud computing. Cloud computing is a heterogeneous system and it holds and processes large amount of complex data. Scheduling tasks efficiently can lead to better performance and more throughputs in the system. In this paper in order to(More)
