A High Throughput Anticollision Protocol to Decrease the Energy Consumption in a Passive RFID System

Abstract EN

One of the main existing problems in Radio Frequency Identification (RFID) technology is the tag collision problem.

When several tags try to respond to the reader under the coverage of the same reader antenna their messages collide, degrading bandwidth and increasing the number of transmitted bits.

An anticollision protocol, based on the classical Binary Tree (BT) protocol, with the ability to decrease the number of bits transmitted by the reader and the tags, is proposed here.

Simulations results show that the proposed protocol increases the throughput with respect to other recent state-of-the-art protocols while keeping a low energy consumption of a passive RFID system.
