and the agent system are similar to each other, we may apply the rules from the
concept of pheromones to the agent system. However, the direct use of the concept
of pheromones does not give sufficient effects. Therefore, we may suggest a different
approach based on the smell of litter in bins. This kind of system may operate as
follows (Fig.
5.7
):
Information from the bin that it is filled up is sent to the bin model (e.g.
P
1
) placed
in the graph in cyberspace.
The bin model (e.g.
P
1
) generates smell in the graph.
The smell goes through the edges of the graph. The edges which are closer to the
bin have higher concentration of smell, and those which are further have lower
concentration.
The process of the disappearance of smell takes time and once the bin is emptied
it disappears.
The agent (e.g.
A
1
) moving around in the graph feels smell and uses it for the
navigation in the graph, which is realized as follows:
- The agent is able to distinguish the concentration of smell on every edge.
- The agent getting to the pick (which corresponds to the crossroads) chooses a
further route along the edge through which the highest (in this place) concen-
tration of smell gets.
- If a few edges in the pick have the same or higher concentration of smell, then
one of these edges is chosen randomly.
In effect, the agent heads for the node with the filled bin.
The agent directs the robot it manages to follow the route in the city which
corresponds to the relocation of the agent in the graph.
The above example of the robot management uses the concept of attracting smell as
a method for the navigation of the agent (and the robot) in a given environment in the
