Method for transmission in a multihop ad hoc IP network

This transmission method comprises transmitting a message from a source transmitter node to a final destination node through a succession of jumps from one sender node to a receiver node immediately following, in which is implemented a ) a reliability of the management mechanism comprising applying a message retransmission Act jump, the sender node to the receiver node, which law includes rules for non retransmission of messages, leading to the non-retransmission of message b) one of the nodes congestion management mechanism providing a flow restriction (a) sending a sender node to a receiver node after a receiving node congestion information addressed to the sender node, said mechanism being applied only hop by hop, the congestion information being transmitted as a receiver node to a sender node on a single jump for limiting the flow rate of the single node transmitter to the receiver node only.
