Introduction

• RFID system overview

Applications Combine RFID data with application
logic Provide persistence
Combines with application logic
Middleware Distributes filtered RFID
data Acquires raw RFID data
Acquires raw tag reads, filters and deliver them
to applications
Readers Identify tags
Identifies tags using radio-frequency

Introduction

• Analysis the requirement for RFID M/W
• Manage large deployments of readers
• Manage the amount data of readers capture
• Middleware design
• For application needs
• For constraints of passive RFID

Related Work

• EPC Network (EPC Global)
• Savant (Auto-ID Center)

6
Requirement for application

• Application Requirements
• RFID data dissemination
• single application, multi application, business
  partners
• ex) supports different latencies
• Data filtering and aggregation
• Rather than raw streams of RFID data
• Reading from and writing to a tag
• Reader integration in IT-service management
• For increase reader (change, configuration)
• Privacy

7
Constraints of passive RFID

• Characteristics of RFID
• Limited communication bandwidth
• Exist 100 readers in 15 channels
• Readers need to coordinate their activities
• Restricts the number of tag that identified per
  sec
• Reliability issues
• False negative reads (by collision or
  transmission errors)
• Tag memory
• Impacted by the memory structure on the tags (a
  single random identifier or identifier that
  contains object info)
• Heterogeneous reader landscape
• Diverse computing and networking capabilities of
  readers

RFID middleware design(1)

• Filtering and Aggregation

RFID middleware design(2)

• Messaging
• - Decouple between reader and application
• Full content-based routing
• Carry out the filtering within the messaging
  system (by reader ID, tag ID, tag data)
• Subscription feedback mechanism
• Determine whether applications are interested in
  the RFID data readers produced
• Switching off completely to make bandwidth
  available to another reader
• Filtering
• No longer carried out in software , but over air
  interface
• Reliability
• POS system, magic medicine cabinet (real-time)

RFID middleware design(3)

• Reading from and writing to a tag
• - Writing to an RFID tag as easy as writing data
  to a hard disk
• VTMS (Virtual Tag Memory Service)
• Shield the application from the particularities
  of RFID tag memory
• Limited memory size, different memory organization

11
RFID middleware design(4)

• Reader integration in IT-Service Management
• Integration of RFID readers in an existing
  IT-service
• Perform change, release, configuration management
  
• Requires methods to query and modify
• Configuration of a reader
• Remotely update the software on a reader
• Exception reporting functionality

RFIDStack

• Middleware platform
• Messaging component
• feedback mechanism
• built-in security feature
• support seven different types of readers
• filter and aggregate types
• No support for IT service management
