Abstract
The present invention relates to a time slot allocation apparatus and method for preventing collisions between time slots in a TDMA-based RFID network. The time slot allocation apparatus allocates time slots, obtained by dividing a same frequency band into unit time slots, to RFID readers for reading identification codes of RFID tags () in the TDMA-based RFID network. A time slot allocation device () allocates time slots required for communication with the RFID tags to a plurality of RFID readers () provided in the RFID network. A collision prevention device () performs control such that the time slot allocation device allocates time slots to the plurality of RFID readers while distributing different and non-successive time slots to adjacent RFID readers, thus preventing collisions from occurring between time slots allocated to the RFID readers.
