IEEE (Institute of Electrical and Electronic Engineers) Citation Style is often used in the disciplines of engineering, electronics, telecommunications, computer science, and information technology.
IEEE has a simple form of in-text citation wherein only a number placed within brackets is included in-text. This number will correspond to the numbered reference on the References page, and the numbers will ascend in order of the reference's appearance in the text. However, if you reference a citation more than one time, you reference it with the same number in which it appeared the first time. In other words, your references will only appear once on your References page.
Unlike other citation styles, it is not necessary to include the author's name or the date of publication unless it is relevant to your paper.
