IEEE (Institute of Electrical and Electronic Engineers) Referencing is a numerical referencing system in Engineering. It is simple and unobtrusive in the document and has two main features:
The citation is a number:
A number is given to a source when it is first used in the document
Numbers are assigned based on the order in which the sources appear (i.e., first source to appear is , the second source is , and so on)
Once a source has been given a number it is always referred to by that same number
The Reference list - It is a straightforward numerical list of the sources as they have appeared in the document. Each source is made easily traceable for the reader by including five pieces of data: Author(s), Titles, Publication details, Location, Date.
As indicated in  ... Other studies ,  pointed out that ...
