摘要:

An improved dynamic framed slotted Aloha algorithm (IDFSA) based on the radio frequency identification system is presented. IDFSA divides the tags into different frequency channels in the design period and saves the communication time. In the meantime, IDFSA optimizes the real-time slots accounts obtained after frequency division, reducing the colliding efficiency up to 2.67 times, and improves the system efficiency. IDFSA dissolves the problem that the slots amount increases exponentially with an increasing of the identified tags amount. IDFSA has been used in the 433/868/915 MHz system, verifying this method easy and efficiency.
