CloudNetSim - Simulation of Real-Time Cloud Computing Applications

In this paper, we describe our efforts towards realizing CloudNetSim, a simulator of cloud computing infrastructures, suitable for our ongoing and planned research activities in the area of resource management and scheduling for distributed QoS-sensitive and real-time applications. CloudNetSim is based on OMNEST, so that we take advantage of the modularity of the framework, and of many other existing simulation models already available within the framework, including standard network components and protocols, such as TCP/IP. After a brief overview of other similar tools found in the iterature, and the discussion of their limitations, we provide a detailed description of the internals of our simulator, and we show results gathered from a few scenarios demonstrating how its behaviour matches with the one of real simple applications.
