Protocol for synchronising data packets collisions in a wireless network

The present invention relates to a method of synchronising transmission of signals between two nodes in a network comprising at least another cooperating node. The invention consists in, after reception of a clear-to-code signal (CTC) from the one node (B), broadcasting (105) a clear-to-send signal (CTS), which contains at least a timing indication, from the cooperating node (C) to the first node (A) and the second node (B). After reception of the clear-to-send signal (CTS) by the first and second nodes (A,B), a first signal (Sl) and a second signal (S2) are transmitted (107), via the cooperating node (C), respectively from the first node (A) to the second node (B) and from the second node (B) to the first node (A) during at least a common time period depending on the timing indication.
