Efficient multi-objective particle swarm optimisation based ranking system for cloud service selection

Abstract

Cloud computing knowledge achieves the prominent role in elaborating the systems and distributing the applications throughout the internet. Currently, in a cloud computing environment, expedient service selection is essential, since cloud users dependably have assorted sorts of applications with various quality necessities. The cloud service ranking has four phases: receiving user's requirement, estimating the quality of service (QoS) attributes by monitoring, selecting candidate services and service ranking. Previously, a cloud service ranking based on QoS attributes employs both essential and non-essential requirements and both objective and subjective assessments. Existing cloud service ranking system experiences multifaceted nature issues. In order to overcome these issues the authors' proposed technique is introduced. Their system comprises of three stages which are screening, optimal pseudo services and clustering process. In the Screening, the appropriate candidate's services are selected. In the wake of screening, candidate's services are optimally chosen to utilisean enhanced multi-objective particle swarm optimisation algorithm. Finally, for the purpose of ranking the selected candidate's services are clustered by hierarchical clustering algorithm and pick the best services. The proposed technique is actualised in Java with CloudSim.
