Design of a child localization system on RFID and wireless sensor networks

Radio frequency identification (rfid) and wireless sensor networks are wireless technologies that rapidly emerge and show great potential. combining rfid and wireless sensor networks provides a cost-efficient way to expand the rfid system's range and to enable an rfid system in areas without a network infrastructure. these two technologies are employed to build a wireless localization system in a children's theme park. the main purpose of this child localization system is to track and locate children within a certain range near some landmarks in the park. the design experience in this project can be exported to other applications such as object tracking and surveillance. copyright © 2010 chao chen.
