RFID Agent Middleware Architecture

Accomplishments

  • General-purpose agent architecture developed:

– Uses multicasts, XML – Packetization implemented on top of multicast layer – Lots of functionality abstracted to architecture – Architecture de-centralized; no longer a single point of failure

  • RFID application in progress:

– Reader Agents (Gen1 & Gen2) – Database Agent, RFID database schema – GUIs – Test Interface

  • Fielded for test/use at RFID Center.

RFID Agent Middleware Architecture

Near-Term Goals (Spring 2006)

  • Add Gen2 reader support (Alien working,

Symbol alpha, ThingMagic almost)

  • Adding support for tag-printer agent(s)
  • Improve analysis queries and GUI
  • Scalability – decentralize backbone to enable

multiple concurrent instances of application

  • Provide SNMP interface to system
  • Fix bugs as they are identified
  • Performance and scalability testing
  • General release to RFID Center

RFID Agent Middleware Architecture

Longer-Term Goals

  • Add mobile platform support
  • Add sensor support
  • Add security/access control features to agent

architecture

  • Add menu-based natural language interface (MBNLI) for

query creation and other logic

  • Add “intelligence-on-the-fly” capability to agent

architecture

  • Release architecture, RFID application as open-source
