Towards an IoT network testbed emulated over OpenStack cloud infrastructure

Internet of things (IoTs) and the development of its network protocols, network architectures, and applications, are hot research topics recently. However, testing and building such a real-time IoT application takes a high cost due to the heterogeneity and a variation on the number of IoT devices, i.e., the scalability. The work in this paper, instead, reduces such the cost and focuses on the development of an IoT emulation testbed to deploy different IoTs applications, to evaluate and measure the performance of IoT network protocols, under flexible logical network architectures, e.g., Tree, with reasonable cost. This IoTs emulation testbed has been designed and deployed to run on the OpenStack cloud platform and high-speed network infrastructure in the Data Center of University of Information Technology-VNUHCM.
