“The world isn’t just getting smaller and atter, it is actually becoming smarter.
Today, almost anything—any physical object, process or system—can be
instrumented, inter- connected and infused with intelligence.”

applied coupled with a lack of realism during the design of MANET
are the main causes of MANET running a high risk of failure.”
