RFID Location System Based on Artificial Neural Networks

RFID readers are installed almost at every zone and the transceivers can even track the movement of the individuals. RFID locations systems are often used in real-time location systems that come up with the problems like multipath phenomenon and layout changing. These make locating difficult because most of the location systems are based on fized mathematical calculation that cannot take these situations into account. Using artificial neural network, our location scheme can learn the geography features to adapt to the real world. It could avoid multipath phenomenon effect and flexibly applied to any environment to find the location.
