The Plagiarism

"Computer Networking Handbook" (ISBN: 978-1-58909-666-0) is a 48 page book that "has a simple approach to computer networking, protocols and network hardware". The book is published by Bookstand Publishing (a company that facilitates self publishing), authored by Dr. Ali Jahangiri, with a cover price of $19.95. At roughly 41 cents a page, this book is costly by most standards.

The book starts with a foreword indicating the material was authored by Jahangiri, but many years before the book was published (2009):

"This book is part of my thesis which was written in 2004 - 2005 to accomplish my doctorate degree. However, it has been used as a study guide for computer networking courses widely through the internet till today."

This is troublesome as some of the material in this book, and possibly his thesis, has been plagiarized from material dating back to 1997. This would call into question his thesis and entire doctorate.

The following table details the portions of the book that were taken from other sources, making up 97.8% of the material.

[0] Page 36 and 42 are blank and not included in the total percent. Only page 35, a single graphic, could not be located. It is believed the graphic is not original though.

[1] The description of Peer-to-Peer, Client/Server and Centralized networks is an exact match to several other books including the CompTIA A+ Study Guide (Publisher: Sybex (October 30, 2006)), Network Plus Certification Exam (Aug 11, 2004) and many more. The earliest instance of this text we could find is from MCSE For You Corporation, "Last Update: 20 April 2000". Their "Net Guide" page, copyright 1999, has the exact text found in portions of this book. It is not entirely clear who originally wrote the text in this chapter, but is predates both Jahangiri's book (2009) and his thesis (2004-2005).

[2] Like footnote [1], most of this chapter comes from the MCSE For You Corporation's "Net Guide". However, the section on Wireless and a few other minor changes are not found in Jahangiri's book. The entire text, with three pictures are taken from Network+ Study Guide. While this link shows "CCNA Study Notes for Exam 640-607" as the title of the PDF, and "Network+ Security Guide" as the first header, we cannot positively match it to the correct title of the book the material comes from. Some of the material from this resource also appears in MC MCSE Network+ Study Guide (N10-004) and CompTIA Network Study Sheet. Each of these resources predate Jahangiri's book (2009) and may predate his thesis (2004-2005).
