It would allow a smoother transition between Section 2 and Section 3, as the modified Section 2 would conclude with the need for a novel smart city service structure.
There are referencing issues with sections as well (e.g. line 213: “As mentioned in 0”) Finally, and most importantly, the format of the bibliography is highly problematic. For many references (e.g. [15], [22], [25]) it is impossible to retrieve the source. For many other sources, the local access path of the file is provided, which again prevents the reader from retrieving the source. All these issues could have been picked up by a simple check. Unfortunately, they are enough for me to recommend to reject the paper, as I consider that submitting a report of scientific quality in this form is unacceptable.
