Research on Experimental-design-based RFID Application Combinatorial Testing Optimization

As a core technology of the internet of things, the radio frequency identification (RFID) technology prevails in many fields. However, the complexity of the actual application scenarios and the diversity of equipment have brought new challenges to RFID real-life deployment and on-site testing. To solve the problem of combinatorial explosion effectively, this paper proposes a combinatorial testing method for optimizing the RFID performance by experimental design. With the orthogonal design method under the conditions of multiples levels and multiple factors, it helps users to choose the representative test cases equally to simplify the tests, quickly set up the system model of inputs and outputs, and acquire the main and secondary factors and patterns influencing the test results. The case study on RFID tag performance combinatorial test shows that the combinatorial testing method is valid for optimizing the test cases in on-site RFID applications, and that it can also provide useful reference to the deployment of RFID systems.
