5. BENEFITS Low latency, high performance Interact with each other without being connected to the cloud Works anywhere, anytime No account registration !5
6. !6 DEVICE-TO-DEVICE COMMUNICATION IS HARD
7. !7 No central infrastructure to administer connections and interactions Connections are unreliable and volatile Fast-changing network topology WHY?
