—Accurate availability and performance analysis are important requirements to guarantee quality of services (QoS) for cloud users. In this paper, we develop an analytical performance and availability model using interacting stochastic sub-models. Each sub-model captures a specific aspect of cloud centers. The key performance metrics such as task blocking(More)
—Smart grid is expected to improve the efficiency, reliability and economics of current energy systems. Using two-way flow of electricity and information, smart grid builds an automated, highly distributed energy delivery network. In this paper, we present the requirements for intrusion detection systems (IDSs) in neighborhood area network (NAN) as a(More)
—Performance modeling of cloud computing centers is a challenging task due to complexity, shared resources and large scale of such systems. Introducing heterogeneous resources and workloads make the analysis even more complicated. In this paper, we propose a layered stochastic performance model applicable to cloud centers with wide range of heterogeneous(More)
