An RSN Tool : A Test Dataset Generator for Evaluating RFID Middleware

Evaluation of RFID middleware is a complex process due to its cost for constructing a test bed involving RFID readers and tags. An input dataset of the RFID middleware is a tag event stream from connected readers. A randomly generated dataset can be considered for stress testing, but this cannot guarantee whether the middleware can provide correct answers on given dataset. To enable this, the dataset should be meaningful to represent tags’ activities based on business rules. This paper presents an RSN Tool which generates semantic datasets based on tags’ behavior. The basic idea is to virtualize RFID environments in a point of business processes. To do this, the RSN Tool provides a modeling of real world RFID environments using graph representations, and execution mechanisms of tags’ movements under several business rules. The experimental result shows that the RSN Tool can create a semantic valid dataset which reflects tags’ behavior.
