Transmission method in an ad hoc multi-hop IP network

摘要

The transmission method according to the invention includes transmitting a message from a source transmitting node to a final receiving node through a series of hops from a transmitter node to an immediately following receiver node, using:
a) a reliability management mechanism including applying a retransmission law of the message on the hop, from the transmitting node to the receiving node, said law including message non-retransmission rules leading to the non-retransmission of the message,b) a mechanism for managing congestion of the nodes providing for a limitation of the throughput (λ) for sending from a transmitting node to a receiving node following congestion information from the receiving node sent to the transmitting node, said mechanism being applied only hop-by-hop, the congestion information only being transmitted from a receiving node to a transmitting node over a same hop to limit the throughput of only the transmitting node toward only the receiving node.

1. A method for transmitting information in an ad hoc multi-hop network including the transmission of a message from a source transmitting node to a final receiving node through a series of hops from a transmitting node to an immediately following receiving node, using:
a reliability management mechanism, the method including:
upon compliant receipt on each hop of at least one message by the receiving node, sending an acknowledgment message to the sole transmitting node; andapplying a retransmission law of the message on the hop, from the transmitting node to the receiving node, said law including message non-retransmission rules leading to the non-retransmission of the message, and b) a mechanism for managing congestion of the nodes providing for a limitation of the throughput (λ) for sending from the transmitting node to the receiving node following congestion information from the receiving node sent to the transmitting node,
wherein the method further includes applying the congestion management mechanism only on a hop-by-hop basis, the congestion information only being transmitted from the receiving node to the transmitting node over a single hop to limit only the throughput for sending from the transmitting node to the receiving node.
