The method of the invention envisages determining, for each packet that is to be transmitted/retransmitted, through an LLC communication protocol, which is the top sublayer of the datalink layer of the ISO-OSI model, (LLC logic) autonomously, node by node, the specific communication apparatus to be used from the ones available on the single node, to which subset of the nodes said packet is to be transmitted (routing logic), i.e., the number and the set of neighbouring nodes to which it is to be transmitted, the specific communication apparatus to be used from the multiple ones that may be available, and the maximum number of retransmissions to be made, by using a decentralized self-learning algorithm that enables each node to learn and select dynamically the best operating mode, according to the number of transmissions already made.
