How to cite multiple sections of book using IEEE Citation Style
If youe thesis is going to be published by an IEEE journal or conference, then you should look at that venue's site for instructions on such details. Otherwise, look to your institution's guidelines. If there are none, then you may do what you want. Personally, I would avoid cluttering my BibTeX files with multiple @inbook citations which only differ in the referenced page numbers and use the latter citation reference you suggest if it is supported by the IEEE style file.
