Effective Collision Avoidance Mechanism for RFID Tags
RFID is technologies which transfer data between electronic tag and reader by radio frequency for the purpose of database auditing. RFID systems are used for automated identification. It is also called Automated Data Collection technology. In this, binary tree anti-collision protocol search all possible tags based on their unique identification numbers. Once a tag has been completely identified, it will be eliminated. For reset, the authors use unique sequence of no.'s for provide synchronization between reader and tags. The mode of operation is the reader inquiring and tag answering. Implementation of anti collision protocol is done by VHDL language using Xilinx software.
