A High Time-Efficient Missing Tag Detection Scheme for Integrated RFID Systems

Round 1

Reviewer 1 Report

This article discusses an interesting problem (missing tag problem). I have found following issues, which are required to be address.

• First Introduction part is too lengthy, first two paragraphs should be deleted;
• The formal analysis part is vague, more details are required.
• More experimental results are required to be added;
• The problem definition part needs to be more formal;
• Recently physical security of the Tag has become a real problem, authors need to consider that.

Reviewer 2 Report

The authors present a missing tag detection technique involving multiple readers. The models are clearly written and the experimental studies with good results have demonstrate the performance. My further concerns are summarized as follows.

1. Since the authors claim the proposed method outperforms the state of the art, please give the competitive peers in a table with their key parameters including time-efficiency.
2. A model of the missing tag detection technique is required to give the readers an intuitive understanding.
3. The Language of this paper needs to be further polished. May presentations are incorrect.

Reviewer 3 Report

This work proposes a method for missing tag detection, targeting multi-category and multi-reader RFID scenarios. The proposed method optimizes the parameters of each reader to personalize the reader’s settings and proposes a collision elimination algorithm to detect missing tags simultaneously. The paper has well-defined the problem, developed the method, and conducted the simulation. But the authors shall include more descriptive explanations of graphs. For example, Figure 1 shows one example of reader deployment. But what does it mean? How to interpret it? Moreover, the authors are recommended to include a comparison table between their MMTD method and other methods, which can highlight the performance of their method.
