Abstract :
Collision is a problem which degrades the performance of the radio frequency identification (RFID) system while multiple tags are communicating with the reader simultaneously. Currently this problem is handled by various procedures such as framed ALOHA protocol, binary tree protocol, tree walking algorithm or using spread spectrum modulation scheme. The current solutions are slow, power wasting and cannot solve collision problem in better aspect. The proposed system eliminates collision while multiple tags are responding to the reader under its network and provides better power savings than existing systems.
