The communication environment refers to the mechanisms and protocols through which agents exchange information and interact with each other.
Agents can perceive and respond to changes in their surroundings, such as the availability of resources. For instance, in wolf sheep predation model, if the sheep encounters a patch which do not have grass in it, it approaches to other patch in search of grass.
Similarly in Hurricane Evacuation Model, when individuals (agents) encounters damaged roads, they look for another undamaged road for evacuation.
