Almost all the IEEE Conferences are WITHOUT review.
It is enough for the organizers to ensure the Co-sponsorship of IEEE and then it is enough to start advertisements by email or in the local scientific magazines of their country that they are authorized to run an "IEEE" conference (or "IEEE" multiconference). They print out great advertizing posters with a very big picture of IEEE logo. Sometimes they make several phone calls. They know that the personal phone calls are better than the Email Spam. I was called by a colleague last December to participate in his IEEE conference. I told him that I am not an expert in the field of this conference, but he insisted that I am inside the scopes of the meeting. I sent them 5 papers. All of them passed without review.
When I asked them why I did not took any review, he told me "your papers were really excellent". I do not say that my papers were bad, but at least, I wanted to have some opinions, some comments, some ideas. I was waiting for them, but nothing. Finally, we made some negotations with registration fees. With 5 accepted papers I had to pay 2000 Dollars. Fortunately, my "good" colleague made a generous discount for me and I paid only 1500 Dollars providing that I would say good comments and positive opinion for his IEEE conference to my friends. I did it. However, I am writing you now the truth for this bogus IEEE conference.
