(English Abstract)
This paper discusses the problem of handling active RFID tags under standard RFID middleware and proposes an extended platform for supporting active tags. The Application Level Events specification provides standard APIs for the RFID middleware. The basic roles of the specification are filtering and collection for the RFID data. However, it does not consider characteristics of active sensor tags such that repeated requests to the active tags will exhaust the internal battery of the tags. Moreover, the specification does not support the asynchronous communication, such as alert event which is a unique feature of the active sensor tags. This paper proposes an extended RFID middleware platform to support handling of the active sensor tags. To do this, we present new APIs for handling active tags based on Application Level Events 1.1 specification. The designed Notification API and ANSpec provide the way to get notification messages asynchronously from the active tags. We also provide extended APIs which enables discreet query to the active tags for reducing repeat reports. The implementation shows that the extended middleware platform generates alert event for the active tags. The main contributions of this paper are to define an extended APIs and develop a middleware platform for handing active tags as well as supporting passive tags.
