physical range required of locational tracking, 5G networks can send data to the edge of the cloud to store data. An application like smart watches that track patient health data can be used to call the nearest hospital if the patient shows a negative change in vitals. Fog node networks can be implemented in car automation, keeping data about the car and its surrounding states secure. By authenticating the fog nodes and the vehicle, vehicular handoff becomes a safe process and the car’s system is safe from hackers. Machine to machine verification Many systems that do not require a human user as part of the system also have protocols that mutually authenticate between parties. In unmanned aerial vehicle (UAV) systems, a platform authentication occurs rather than user authentication. Mutual authentication during vehicle communication prevents one vehicle's system from being breached, which can then affect the whole system negatively. For example, a system of drones can be employed for agriculture work and cargo delivery, but if one drone were to be breached, the whole system has the potential to collapse.
