A bidirectional radio frequency identification (RFID) network system and
method are presented. The system allows users to configure, monitor, and
manage different sensor devices by using a graphical user interface
real-time. The reconfiguration is done through a network management
computer at the top system level that receives user input, generates code
images according to the user input, and appropriately routes the code
images to sensor routers that directly control the sensors. If the system
is multi-layered, some code images are also sent to the
intermediate-level network management computers. The system allows users
to not only monitor a business flow but react to problematic situations
quickly by adjusting the workflow. The aspect-oriented nature of the
system allows users to reconfigure the system based only the
Functionality aspects without worrying about the Partitioning aspects
(e.g., how the network and the sensors are physically connected).
