PET: Probabilistic Estimating Tree for Large-Scale RFID Estimation
Radio Frequency IDentification (RFID) technology has recently attracted dramatic attentions from the research community. A typical RFID system consists of RFID readers, RFID tags, and the middleware software to support proper working of the system. An RFID tag is a small microchip capable of wireless communication, which transmits data in response to interrogation by an RFID reader. RFID tags, each with a small size of memory to store its unique ID number as well as other related information, are usually attached to real objects for explicitly labeling those objects. An RFID reader can thus identify and itemize the objects by verifying the unique IDs of RFID tags attached to them.
