RFID Middleware
RFID Middleware
Software that bridges RFID hardware and enterprise applications. It is the primary means of data gathering for any RFID deployment.
RFID middleware assists with the filtering, aggregation, and routing of RFID data. The middleware has built-in business rules that monitor the data stream and direct data to appropriate enterprise systems.
GSN
GSN is a software middleware designed to facilitate the deployment and programming of sensor networks.
Using GSN, now you can leave all the nifty sensor network details behind and focus only on the high level application logic. Thanks to GSN's open API, you can quickly write sensor network applications by leaving the tedious task of managing low level hardware dependent details to GSN.
Furthermore, using GSN you can even develop sensor network software exploiting several heterogeneous sensor networks: imagine joining pictures coming from your wireless camera, tag IDs coming from a RFID reader and light readings from two other wireless sensor networks.
GSN is developed based on the observation that most of the logical requirements of the applications developed for sensor networks are similar. Having each sensor network deployment using its own custom software not only increases the costs and times of deployment and development (reinventing the wheel for each application), but also makes it difficult (almost impossible in some cases) to integrate several sensor networks together (especially when managed by different authorities).
GSN is designed to make the sensor network application development a pleasure. The applications based on GSN are hardware-independent making the sensor network changes invisible to the application, for instance you can change the underlying sensor network from the Mica2 nodes to the BTNodes (with compatible sensing boards) without ever touching a single line of code in the application.
