IoTNetEMU - A Framework to Emulate and Test IoT Applications

Testing and validating IoT applications is inherently complex due to the number of devices involved that should communicate with each other and with cloud infrastructures. Models, emulators and testbeds are used to validate parts of the solution, but the gap between simulations and live experiences is still deep. To minimize this gap, we propose IoTNetEMU, a modular framework that combines several open-source components to provide a validation tool for developers and researchers. This paper describes the framework, shows how it can be used to test and validate an IoT application with minimal changes, and compares results collected using it with results from real devices.
