In this paper, we propose embedding RFID tags in trees in a forest to track hikers. Hikers are equipped with RFID readers, which read from and write to tags. Specifically, as a hiker moves through the forest, his/her reader leaves his/her ID and increasing sequence numbers (SNs) in tags. This creates a digital trail that allows the hiker to backtrack(More)

—We propose a neural networks-based learning mechanism for tracking in an RFID tag field. As users move through the field to a desired destination, they train localities of tags, creating digital trails. Later on, users seeking the destination, but without knowledge of any path, can follow the digital trails. Training information (weights from the neural(More)
