The nodes automatically choose the most suitable and
reliable way of communication for themselves through intercommunication
with adjacent nodes.The nodes at both ends
of each segment receive such data and transmit them to
user by using conventional communication channels. Any
gateway acts at the same time as the substitute of any other
gateway, and, as it is the case for the detecting nodes, they
substitute each other in their function in case of breakdown
so that the probability of shut-down of the system due to any
failure in any one of the gateways is minimized. Thus, this
unique feature is an additional measure against any eventual
tactical deception attempts.
