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 software RFID Agent Middleware Architecture
