Abstract:
Cloud computing makes the delivery of computing resources over the Internet as services. As there are many providers in the market, it is necessary to monitor their performance. Several mechanisms for monitoring service quality of providers have been reported in the literature. But, it is not possible to monitor the entire cloud system by a single monitor. Hence, there is a need for a mechanism to share the performance metrics across a large geographical area. In this paper, the authors propose a mechanism called Bayesian Trust Distribution Mechanism (BTDM) for sharing the performance metrics as trust scores across an extended geographical area. The proposed BTDM also checks the reliability of the received scores based on their previous experience and adjusts them based on the reliability of sender. BTDM was tested using simulations and the results show that it performs better than the other mechanisms reported in the literature.
