With increasing AoI, the fan-out of events increases significantly.
This leads to message loss on the ad hoc communication
medium, as more and more collisions occur. Figure 5f
shows the ratio of events that were lost on the ad hoc
communication channel. In the case of the hybrid scheme,
this is solely due to collisions or disconnected network parts.
For the adaptive scheme, this ratio is slightly increased by
the impact of the protocol switches.
