There are two parts in this talk. In the first half we discuss through examples the concept of choice-driven information-based control system. The trade-off between communication complexity and control cost for a prototypical system is explored. In the second part, we present results related to synchronization of distributed users by summarizing recent advances in protocol sequences research, including the concept of user-irrepressibility and CRT sequences. We highlight some potential applications of these protocol sequences in communication systems as conclusion.
