Abstract :
The emergence of UHF RFID as one of the dominant technology trends has posed numerous unique challenges to researchers. This letter presents a novel, theoretically-grounded collision arbitration protocol, called TPC-CA, which optimally controls transmission power of RFID interrogators and thereby reducing redundant interrogator collisions
