<p>The present invention relates generally to communication networks and more specifically to methods and devices for data communication over a communication network having a medium shared between a plurality of communication nodes. The method comprises: obtaining an estimated frequency at which a second communication node is expected to request an access to the medium to send data to an addressee node; requesting, based on the estimated frequency and prior to the second communication node, an access to the medium to be granted a transmission opportunity 60; and allocating a first transmission period 63 of the granted transmission opportunity, to the second communication node for the latter to send the data to the addressee node. In that way, the first node anticipates requests for medium access from the second node, thus reducing risks of collision.</p> |
