1. ITU-T WORKSHOP “ICTs: Building the Green Cityof the Future” (Shanghai, China, 14 May 2010) Smart Tracking: Usage of IPv6 in RFID System for Global Mobility Labonnah Farzana Rahman Dept. of Electrical Electronic and Systems Engineering Universiti Kebangsaan Malaysia, 43600 UKM, Bangi, Selangor, Malaysia

2. Agenda • Introduction • RFID Technology • Features of IPv6 • IEEE 802.11b Standard • Proposed System • Objective • Milestones • Conclusion

3. Introduction • The ‘smart city’ is the ability to access any application at anytime from anywhere • Smart Cities should implement • e-health • e-government • e-commerce systems • Cities become “Smarter” with • Object Identification • Network of things • High speed Wireless Network • Monitoring by Sensors • Cities become “Green” with • Low power consumption

4. RFID Technology • Object Recognition/ tracking system • RFID system consists • transponder (i.e., the tag itself) • transceiver (i.e., the reader) • To track any object it uses an EPC • An EPC is either 64-bit or 96-bit identifier • Header-2 bits • EPC Manager- 21 bits • Object Class- 17 bits • Serial Number-24 bits H EPC Manager Object Class Serial Number Figure 1: EPC 64 bit

5. Features of IPv6 IPv6 128 bits Subnet Prefix Interface ID 64 bits 64 bits Figure 2: IPv6 Address format • Bring the idea “Network of things” • Ease of Deployment • Global Mobility • Multicast/Anycast • Security • Scalability • 128 bit address structure(16 octets) • Subnet Prefix / Network Prefix • Interface ID- EUI 64 bit

6. IEEE 802.11b Standard • High speed Wireless Networks or Wi-Fi • Extension of IEEE 802.11standard to IEEE802.11b standard • Applies to wireless LANs • Provides 11Mbps to 55Mbps Data transmission rate • 2.4 GHz ISM frequency band

7. Proposed System • RFID experiencing problem • Vendor Specific • High implementation cost • Local mobility • The proposed System will • Use WNIC instead of Reader • Use IPv6 in RFID system • Use IEEE 802.11 standards, perhaps better known as WiFiProtocol • A low power transponder IC

8. Objective To design a high speed, efficient and low power tag IC using mapped EPC-IPv6 address for the future green city To employ IEEE 802.11 standard for WLAN instead of proprietary standard of RFID Reader for a smarter city To develop a Computer Application to extract data from the tag

9. Milestones

10. Phase 1: Map EPC 64bit with IPv6 Address • Total 64 bits of EPC directly mapped into IPv6 address structure • Each RFID tag becomes addressable in the IPv6 network EPC – 64 bits IPv6 128 bits Subnet Prefix Interface ID 64 bits 64 bits Figure 3: IPv6 Address format after mapping with EPC

11. Phase 2: EPC –IPv6 tag Integrated Circuit Antenna VCC RF Front End EEPROM EPC- IPv6 Address Rectifier Low Power Digital Logic Demodulator Modulator Figure 4: Block diagram of the proposed EPC-IPv6 Tag

12. Phase 3: EPC –IPv6 tag Communication with WNIC WiFi Network RFID Tag with Mapped EPC-IPv6 Wireless Network Interface card Figure 5: EPC-IPv6 Tag communicate with WNIC through WiFi

13. Phase 4: EPC Receiving Technique EPC – 64 bits IPv6 128 bits Extract EPC-64 bits Subnet Prefix EPC-64 bits 64 bits 64 bits Figure 5: IPv6 Address format after EPC Extraction A computer Application will extract the EPC portion from the mapped EPC-IPv6 address structure

14. Conclusion • By Using the Proposed System • A low power tag IC will be developed to make the city “Green” • The cost of efficient RFID tagging system for future smart city will be reduced • Possible to find out the physical location of any objects, which is one of the prime element of smart city • Provide Global Mobility • Increased Scalability, Reliability, and Security for the future “Green” city
