An Optimized Query Tree Algorithm in RFID Inventory Tracking - A Case Study Evidence

Free registration required

Executive Summary

One of the challenged technical issue faced in inventory tracking applications with Radio Frequency IDentification (RFID) implementation environment, is the collisions due to responses from multiple tags on the shared channel between reader and the tags, which consumes further the energy as well as the delay in tag identification process. To avoid collisions by some anti-collision algorithm means, may create large amount of data, adding complexity at the circuit level and also consumes energy for on-going transmissions. Therefore, an optimized anti-collision algorithm can be designed to avoid the collisions with minimal amount of data transmissions for lowering the communication overhead as it is critical for wireless battery operated devices.
