Abstract
The method improves data exchange on a wireless communication medium accessible by a plurality of nodes via a contention mechanism, the plurality of nodes comprising legacy nodes and a collaborative group of nodes, each node of the collaborative group being provided with a first and a second MAC address. The method comprises, upon successful contention at a first node of the group, at the first node: determining if a communication from a source node of the group to a legacy node is required, and in such a case, selecting the second MAC address of the source node as source address for issuing a request to access the medium (RTS), and, upon reception of a medium access authorization (CTS): transmitting first data to the legacy node using said second MAC address, and transmitting second data inside the group using said first MAC address.
