To have a better QoE , FRAN is adapted with four transmission modes such as the following:Device-to-device relay mode

Distributed (local) coordination mode

Centralized (global) mode

Macro Remote Radio Heads (MRRH) mode [8]

The Fog user devices dynamically decide the mode of transmission based on the communication location, the distance between the communicating devices, computing and caching capacities and the Quality of Service (QoS ).

7.5.3 Handover Administration in FRAN

Administering the handover in any mobile communication is the most important but critical technique to guarantee an unfailing network experience. There are broadly two types of devices based on the mobility in mobile communications, viz the high-speed Fran User Equipment (FUE) and the low-mobility Fran User Equipment. High-speed FUEs need to use MRRH mode that has large geo coverage and reliable network, whereas the low-mobility FUEs can use a small-range radio head. Radio link failures and unwanted handovers are always possible in mobile networks due to a small area of access. Fronthaul gets overloaded due to frequent and rapid handovers affecting the whole network communication. So, the access points and radio heads can collaborate with FUEs in the decision-making of the transmission modes.

One of the main characteristics of 5G technology which yields to QoE is its ability to serve heterogeneous and diversified applications using the same communication platform. Due to the heterogeneous nature, there are many kinds of packets travelling in the network each with different traffic requirements, for instance, the vehicular network requires a very minimal latency. Context-aware applications are able to serve the types of traffic requirements. Fog computing is possible in any of the Edge nodes, core Cloud network or in third-party data centres where the local baseband units can become the computing servers. Computations happen in two ways such as communicational ones or the traffic flow ones.

FRAN attempts to take complete advantages of the Cloud computing model, diversified networks and Fog computing capabilities. The four types of Cloud are:a.Global centralized communication and storage Cloud which is the same as of the centralized Cloud
