Schema illustrating the activity of the agents
A
g
1
and
A
g
2
Agent of type
“one”
(
A
g
1
). This agent is created by the agent
A
g
0
and is able to
travel between the nodes. It is responsible for searching for the node which has
an overflow of the resource and which could send it to the home node of the agent
A
g
0
, which created a given agent of type
A
g
1
.
Agent of type
“two”
(
A
g
2
). It is created by the agent
A
g
0
and can travel between the
nodes. The agent is responsible for searching for the node which has an underflow
of the resource and could take it from the node with an overflow.
The operation of the whole system results froma definition of the function of different
types of agents. A scenario of the activity of the agent
A
g
1
may be presented in the
following stages:
1. The agent
A
g
0
states that there is an underflow of the resource (which is below
the lower limit) in the home node in which it resides.
2. The agent
A
g
0
checks the amount of the resource in the neighbouring nodes. If
it finds the one that has an overflow of the resource and is able to send it, then
the agent negotiates the amount of the resource to be given and then a process
of sending takes place. However, if there is no potential “giver” of the resource
among the neighbouring nodes, the agent starts searching for the potential “giver”
among the nodes placed beyond the neighbouring nodes.
