ABSTRACT: Cloud computing has emerged as a new style of computing in distributed
environment. An efficient and dependable Workflow Scheduling is crucial for
achieving high performance and incorporating with enterprise systems. As an
effective security services aggregation methodology, Trust Work-flow Technology
(TWT) has been used to construct composite services. However, in cloud environment,
the existing closed network services are maintained and functioned by third-party
organizations or enterprises. Therefore service-oriented trust strategies must
be considered in workflow scheduling. TWFS related algorithms consist of trust
policies and strategies to overcome the threats of the application with
heuristic workflow scheduling. As a significance of this work, trust based Meta
heuristic workflow scheduling (TMWS) is proposed. The TMWS algorithm will
improve the efficiency and reliability of the operation in the cloud system and
the results show that the TMWS approach is effective and feasible.
