The sharp increase of RFID tags and readers require dedicated middleware solutions that manage readers and process event data. In this paper, we demonstrate a RFID middleware called LIT ALE Manager system with key features and also illustrate overall functional components of the middleware system with implementation techniques.
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… (More)
—This paper presents a noble RFID data generation tool to enable efficient and low cost testing of the RFID middleware. RFID systems have been widely used in many business areas such as supply-chain management and yard management. As a key component of RFID system, the RFID middleware should be carefully evaluated from various environments. However, taking… (More)
In RFID system, RFID tags emit data continuously and sensed by RFID access point. RFID data are appears in form of stream data items to RFID host. By this RFID data collecting, RFID system provides identification information of objects which tags attached to users. However, some applications require not only identification information but also monitoring… (More)
This paper investigates the problem of inconsistent states of radio frequency identification (RFID) tag data caused by incomplete execution of read/write operations during access to RFID tag memory. Passive RFID tags require RF communication to access memory data. This study is motivated by the volatility of RF communication, where instability is caused by… (More)
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… (More)
