Flexible and Adaptive Testbed for 5G Experimentations

5G mobile communication technologies with extreme cellular capabilities have gained a considerable attention at both industrial and academic sectors in the last decade. For this, researchers need to experiment different complicated architectures and advanced test scenarios with the help of testbeds. In this context, OpenAirInterface (OAI) has been introduced as an open source platform to implement testbeds for 5G experimentations based on Software Defined Radio (SDR) and general-purpose processors. However, the required manual configurations and operation of different nodes in OAI-based testbeds force researchers to spend more effort and time in building and operating the testbed rather than focusing on testing their new ideas and proposed algorithms. Thus, an innovative management platform is designed and developed to flexibly configure, operate and manage different OAI nodes in a centralized and remote manner. The platform is designed to automatically validate the consistency between different related configuration parameters for different OAI nodes, and adaptively operate different configurations and test scenarios. The operation of the developed platform is tested and its performance is validated using different test scenarios.
