The Institute for Electrical and Electronics Engineers (IEEE) is a professional organization supporting many branches of engineering, computer science, and information technology. In addition to publishing journals, magazines, and conference proceedings, IEEE also makes many standards for a wide variety of industries.
IEEE citation format incorporates into content references, numbered in square sections, which allude to the full reference recorded in the reference list toward the end of the paper. The reference list is composed numerically, not one after another in order.
You need to place sectioned references inside the line of content, before any highlighting, with a space before the principal section.
Number your sources as you refer to them in the paper. When you have referred to a source and given it a number, keep on using that number as you refer to that source all through the paper
When citing multiple sources at once, the preferred method is to list each number separately, in its own brackets, using a comma or dash between numbers, as such: [1], [2], [4] or [1] - [4]. Read more at http://www.researchomatic.com/ieee-citation-generator/
