9 Dear Dr. Ahmed Mostefaoui:
11 We have received the reports from our advisors on your manuscript,
12 "Distributed Data Fusion in Sensor Networks : An Asynchronous
13 Iterative Approach". With regret, I must inform you that, based on
14 the advice received, your manuscript cannot be accepted for
15 publication in Cluster Computing.
17 Attached, please find the reviewer comments for your perusal. I would
18 like to thank you very much for forwarding your manuscript to us for
19 consideration and wish you every success in finding an alternative
28 Comments for the Author:
33 Reviewer #1: The paper addresses the issue of distributed data fusion
34 in wireless sensor networks. This is based on a consensus algorithm
35 that allows nodes to converge to some average of sensors measurements
36 of event observed. The authors claim that it is robust to asynchronous
37 measurements and adopt to dynamic topology changes.
38 This work is basically an extension to the author's previous work
39 [14], which they have not explicitly mentioned. This study like the
40 others provides fusion algorithm, which merely provides average of
41 measurements. Therefore, these are applicable to specific applications
42 of wireless sensor networks in which event is detected in a little bit
43 wider range by a number of collocated sensor nodes and change in
44 phenomenon is relatively low. For example, light or temperature
45 monitoring are the target applications for these studies. Hence, the
46 cope is limited. I suggest the authors to incorporate some other
47 fusion functions like deviation or extreme values to make the fusion
48 algorithm more realistic. Moreover, convergence to average of initial
49 states is not the right measure of event information rather it should
50 be converged to recent measurement.
51 There are some grammatical mistakes and writing needs to be improved.
52 Assumptions 1, 2 and 3 are given but it would be helpful to discuss
53 the consequences of these assumptions on the fusion algorithm.
54 There is no comparison with the existing study to see the performance
55 gain of this work. The results should also be provided to show the
56 time taken for convergence in addition to no. of iterations. This is
57 important in case of asynchronous fusion algorithm due to
58 unanticipated communication delay.
63 Reviewer #2: The authors started with a good flow but in the middle
64 and specially in the performance analysis they lost the command. There
65 are a few spelling mistakes and reference are missing in the text. The
66 authors also claimed that they have incorporated the dynamically
67 changing topology, but no results have shown in this regards.The
68 results have not analyzed and explaind properly. Results shown in fig
69 4 and 5 are identical with only axis changed which are not under stood
70 at all. Convergence time is take as the the simulation time which is
71 not correct and need to develop an accurate model. The authors are
72 advised to co-relate their mathematical conclusions with the
73 simulation results accurately and explicitly.
