The invention establishes broadcast channels between neighbor nodes (10) forming ad-hoc clusters of nodes (20). Broadcast channels (25) are established by transmitting (32) a channel establishing request message from the requesting node to inform neighbor nodes of a broadcast channel of said requesting node. The channel establishing request message includes broadcast timing information of the requesting node. Later, the requesting node starts receiving (33) an acknowledge decision message from a said neighbor node to inform the requesting node of a broadcast channel of said neighbor node. The channel acknowledge decision message includes broadcast timing information of the neighbor node. All timing information should have been passed between two or more nodes 10 in the network 20. Accordingly, broadcasting and receiving can be conducted between pseudo-random time intervals that are dependent on the broadcast timing information. |
