Mobility & Handover
Topology of the mobile network is modeled as a graph assuming each UE is connected to only one eNodeB at any time instant. This graphical representation is evolving with time and therefore,
it is obtained by iteratively applying some given operator on the initial graph.
Initial graph X = {E, V} Operator TDynamic nature of graph is expressed by (X, T), where
T:X X recursively.
Operator T is triggered based on UE’s measurement of the received signal level from eNodeB. The existing periodical UE reporting is used.
Operator T is defined by thresholding the measurements.

Further considerations
Prediction of mobility patterns. Self-regulatory and self-governed graphs. Inclusion of analytics, in identifying the pattern.
Replacing the frequent update of UE signal level, with an event-based update.
The actual routing protocol.
