Workflow Scheduling Using IOT Enabled Reputation of Service Providers in the Cloud

Abstract

Cloud computing has become the standard and popular resource provisioning mechanism, in which hardware and software resources are provided in pay per use model. Workflow execution in the cloud is a major research area with lots of open and interesting problems. The key challenges in workflow execution in the cloud are, finding a suitable service provider and effective workflow scheduling. Due to the availability of large number of service providers, selecting a reputed service provider is very essential. Selecting a service provider with low reputation may lead to several problems like incorrect resource allocation, over charging and slippage of deadline, and selecting a highly reputed service provider may cost more. Hence this paper propose a reputation based workflow scheduling strategy that calculates the reputation of a cloud service provider (CSP) based on user rating and the actual performance of Virtual Machines (VMs) obtained using IOT enabled devices. Finally a scheduler is used to schedule the workflow with the service provider having the user’s preferred level of reputation and also recommend a suitable scheduling algorithm for executing the workflow.
