In the Bloor report RFID - from tags to applications, we introduced the different categories that make up the components of an RFID solution. In this report Bloor will look at the first layer of software - RFID middleware - and talk about where the market is leading Sensory Network middleware.

There are three primary motivations behind using RFID/Sensor Network middleware:

• To encapsulate the applications from device interfaces
• To process the raw observations captured by the readers and sensors so that applications see only meaningful, high-level events, thereby lowering the volume of information that they need to process
• To provide an application-level interface for managing readers and querying sensory device observations.

Most RFID middleware available today provides these features.

RFID and other remote sensing technologies provide a level of automation that was not previously possible with labelling technologies such as bar codes that needed human intervention. However, this level of automation requires that the readers and sensors be monitored and managed remotely. A middleware solution that operates at the edges is best suited to monitoring and managing edge devices. Thus, in addition to the three functions described above, an RFID middleware solution should also provide, or at least integrate with, a management and monitoring interface.
