An Improved Scheduling Strategy in Cloud Using Trust Based Mechanism

Authors: D. Sumathi, P. Poongodi


Cloud Computing refers to applications delivered as services over the internet, and the datacenters that provide those services with hardware and systems software. These were earlier referred to as Software as a Service (SaaS). Scheduling is justified by job components (called tasks), lack of information. In fact, in a large fraction of jobs from machine learning, bio-computing, and image processing domains, it is possible to estimate the maximum time required for a task in the job. This study focuses on Trust based scheduling to improve cloud security by modifying Heterogeneous Earliest Finish Time (HEFT) algorithm. It also proposes TR-HEFT (Trust Reputation HEFT) which is then compared to Dynamic Load Scheduling.

Keywords: Trust, Software as a Service (SaaS), Heterogeneous Earliest Finish Time (HEFT) algorithm, Dynamic Load Scheduling
