IntroductionThe ‘smart city’ is the ability to access any application at anytime from anywhereSmart Cities should implement
e-health e-government e-commerce systems
Cities become “Smarter” withObject IdentificationNetwork of thingsHigh speed Wireless NetworkMonitoring by Sensors
Cities become “Green” withLow power consumption

Object Recognition/ tracking systemRFID system consists
transponder (i.e., the tag itself) transceiver (i.e., the reader)
To track any object it uses an EPCAn EPC is either 64-bit or 96-bit identifier
Header-2 bitsEPC Manager- 21 bitsObject Class- 17 bitsSerial Number-24 bits

Proposed System
RFID experiencing problem Vendor SpecificHigh implementation costLocal mobility
The proposed System willUse WNIC instead of ReaderUse IPv6 in RFID systemUse IEEE 802.11 standards, perhaps better known as WiFi ProtocolA low power transponder IC
Objective
To design a high speed, efficient and low power tag IC using mapped EPC-IPv6 address for the future green cityTo employ IEEE 802.11 standard for WLAN instead of proprietary standard of RFID Reader for a smarter cityTo develop a Computer Application to extract data from the tag
