when cor-
relations between the node states become prevailing and long-range order emerges (Figure 2.23).
The transition of the network to the saturation phase shows characteristics of the second-order
phase transition, despite the fact that this transition is more abrupt then those described in Section
2.2.1. Large uctuations in the number of messages in the network (Figures 2.24 and 2.25) and in
the numb ...
