Your code is quite long, and dosn't actually run as an complete example. If you want communications between the children, then create pipes in the parent, and pass them to the children as you fork them, pass the filedesciptor number in many cases.

Look at Parallel::ForkManager + MCE::Shared demonstration for a state-of-the-art solution, or you could just switch to threads from forks, and use thread::shared variables. Or forking with Storable and IPC::ShareLite. Otherwise, start looking at how you make pipes, and pass them off to child processes. Also see FileHandles and threads
