UiTiOt v3: A Hybrid Testbed for Evaluation of Large-Scale IoT Networks

The 21st century is promising to be the era of technology standing out with the thrive of the Internet of Things (IoT). The rapid growth of the IoT leads to an increasingly urgent need of testbed systems. Taking a new step in our long-term research, in this paper, we introduce the third version of our testbed named UiTiOt v3. It is actually a hybrid system which puts virtual wireless nodes together with real physical devices to carry out a variety of IoT experiments. Utilizing the power of the emulation tool, namely QOMET along with the two-layer virtualization based on two state-of-the-art virtualization techniques (Container and OpenStack), our research is towards a large-scale testbed having great advantages in terms of reliability, availability as well as cost-and-effort-effectiveness. After giving details of the overall architectural design, we make a discussion on one typical experiment out of a vast number of test cases we have already done to demonstrate the feasibility and potential of our system.
