Trust Model Based Scheduling of Stochastic Workflows in Cloud and Fog Computing - 2019

Trust Model Based Scheduling of Stochastic Workflows in Cloud and Fog Computing

Research Area:  Fog Computing

Abstract:

The Cloud computing is a lucrative, challenging and beneficial technology in the IT world. The emergence of Internet of Things (IoT) has made cloud computing to be combined with fog computing, in order to avoid latency. These technologies have daring challenges. This chapter focuses on two major challenges, namely security and scheduling of user requests. The security is met by our proposed trust model which includes both direct trust and reputation relationship. This chapter initially, focuses on assuring trusted environment in the cloud. Then a trust model for cloud cum fog environment is proposed. The new trust model would ensure that the user’s requests are serviced with enough security guaranteed level based on the Service Level Agreement (SLA) negotiated with the cloud provider. Based on the trust value computed, the user’s requests are scheduled to the appropriate resource by applying the Trust based Stochastic Scheduling (TSS) algorithm. The trust based stochastic scheduling minimizes makespan of the schedule is achieved for a secured cloud environment
