METHOD OF TRANSMISSION BETWEEN NODES OF A MANET COMMUNICATION NETWORK OPERATING ON AN HF BAND WITH TDMA SHARING OF THE RADIO CHANNEL

摘要

A method of data transmission is between nodes of a MANET communications network on a high-frequency radio channel shared by division of the access time. Each network node is assigned a transmission time slot in a transmission frame, and at least one auxiliary transmission slot is provided and is accessible by a node that has detected the occupation of the radio channel in the time slot assigned to it. Each node is arranged for determining a local time reference for the calculation of the corresponding transmission slot and access to the radio channel, and includes receiving a positioning signal from a geographical positioning system equipping the node, and determining a universal reference time therefrom.

1. 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.
