Method of transmission between nodes of a manet communication network operating on an hf band with tdma sharing of the radio channel

A method of data transmission between nodes of a mobile ad hoc (MANET) communication network on a high-frequency radio channel shared by division of access time, comprising:

• determining a time reference for access to the channel shared by the network nodes, including—at each node—receiving a positioning signal from a geographical positioning system equipping said node, and determining a universal reference time therefrom,
• at a time of network planning, assigning each network node is assigned a transmission time slot in a transmission frame, each of said nodes being arranged for maintaining a local timing reference for determining a corresponding transmission slot, and
• providing at least one auxiliary transmission slot in a transmission frame, which is accessible by a node that has detected occupation of the radio channel in the time slot assigned to said mode.
