Indoor Location System Using RFID and Ultrasonic Sensors

摘要

Ubiquitous Location-Based Services that can detect the location of objects or people anytime and anywhere,and use this as a basis for providing useful services,are emerging important services.Location tracking services are applicable in a wide variety of fields such as logistics,security,industrial autonomy,wireless sensor networks and military tracking.There are various location detection systems using different methods such as infrared,ultrasonic,RFID,UWB and signal strength.This thesis will examine the performance and practical uses of indoor location system which uses RFID and ultrasonic sensors as detection nodes.
