This paper presents an RSN Tool to generate input datasets for testing RFID middleware. As RFID middleware takes an important role in entire RFID systems, its performance should be carefully evaluated under various business conditions. In general, evaluation of the RFID middleware requires a huge cost because the numerous RFID readers and tags need to be deployed to acquire the tag event stream. To facilitate low-cost testing of the middleware, we propose the RSN Tool which provides means of designing a virtual RFID infrastructure and generates a tag event stream automatically for the virtual infrastructure. Using the RSN Tool, we can easily obtain a semantically valid dataset, which captures both physical characteristics of RF communications and business activities of tags’ movements. This is a major differentiation point of our work compared from previous works, which merely create the randomized dataset based on a set of virtual RFID readers. We also discuss a step-by-step usage of the RSN Tool from the creation of a virtual infrastructure to the generation of tag events. The experimental analysis shows that the RSN Tool can create the near-real dataset, which closely reflects business activities of the real RFID infrastructure.
