Abstract :
Dear readers, Time flies! The holiday season comes again. It is time for us to prepare for the annual celebration of Christmas and the New Year. Therefore, I would like to take this wonderful opportunity to send my warmest greetings to all of you. In particular, I would like to send my best wishes to all Editorial Board members, who have worked extremely hard to handle the reviews of submissions for this magazine. My greetings should also go to the publications staff of IEEE Communications Society for their great help to the magazine in publishing papers in a timely manner.
