Poster Abstract: Analysis of RFID Anti-Collision Algorithms using Smart Antennas

چکیده
Recently, the radio frequency identification (RFID) technology has gained significant attention. One of the important performance issues in RFID systems is to resolve the collision among responses from RFID tags from the viewpoint of wireless media access control. We consider two kinds of smart antenna systems to enhance the RFID tag reading rate, namely the adaptive array antenna and the multipleinput multiple-output (MIMO) antenna. For passive tags, we evaluate the performance enhancement of the binary tree splitting algorithm due to smart antennas. For active tags, on the other hand, we analyze the Slotted-Aloha algorithm by employing a two-dimensional Markov chain and assuming a Poisson arrival process for tag responses.
