How to participate in a remote IEEE Conference, due to politics problems in my country?
Contact the conference chair and/or the program chair of the conference as ask how you can proceed. For some conferences this will be possible, and I suspect that IEEE will support reasonable requests. Most large conferences will have the ability to project from remote sources. 

To actually present, however, will require some infrastructure on your end, including some sort of video link (maybe just a web cam) and adequate band width for the link. It might even be possible for a prepared talk to be sent to them prior to the conference by digital media. But you can explore the possibilities with the PC or CC. But you need to do it early. 

A third possibility is to have you not present at all, physically or virtually, but still have your paper appear in the proceedings. 

Happily, digital solutions exist. Sadly political issues make some things hard.
