Cloud Service Broker based Quality Metrics Integration Model for Mobile Environment

Mobile cloud computing is high technology that extends existing IT capabilities and requirements. And it can also access to shareable remote computing resources pool through the network. As the concept of mobile cloud, many providers have served the mobile cloud services using their own service policies. In other words, there is no formal definition of quality criteria for mobile cloud service evaluation. To solve this problem, some quality models are proposed for cloud service evaluation. However, those did not include many metrics to evaluate the services. Even if the model included a number of criteria, it is difficult to identify whether the metrics are proper or not. Furthermore, most existing models were not concerned about mobile characteristics. Therefore, we propose a cloud service integration model to solve the problem as we mentioned above. First, we select additional metrics to satisfy the mobile characteristics. Second, we present an extended SLA model for modeling complex service-dependencies in mobile cloud services. Third, we describe a method of discovering relations between the metrics of service belonging to mobile cloud services and then using these relations for establishing newly generated SLA.
