A method of accessing a communication medium used by a plurality of communication terminals, comprising the following steps, performed by a first communication terminal belonging to a group of communication terminals from the plurality of communication terminals: detecting 410 an upcoming reservation, by a second communication terminal of the group, of an occupancy time interval of the communication medium, determining 420 a timeslot in the occupancy time interval, and transmitting 460 data over the communication medium during the determined timeslot. The method provides improvements in the communications of communication terminals sharing a communication medium.

The disclosure provides an acknowledgement of data received by a communication device, the data being received by data packets, with each data packet comprising a plurality of data blocks. The communication device determines, for a data packet, a number of data blocks whose data can be processed correctly. The communication device further sends an acknowledgement for at least one data block in the data packet if the number of data blocks whose data can be processed correctly is between a first and a second threshold. The communication device also sends, for the data packet, a piece of information at packet level representing the number of data blocks whose data can be processed correctly if the number of data blocks whose data can be processed correctly is lower than the first threshold or higher than the second threshold.

The invention is directed to the optimization of an access to a medium in wireless networks which can be accessed by a plurality of nodes, each node of the plurality of nodes using a medium access mechanism of the Carrier Sense Multiple Access with Collision Avoidance type based on a computation of a backoff value. A specific value is associated with each node of a set of nodes of the plurality of nodes, the specific value of a node being known by the other nodes of the set of nodes. According to the invention, a backoff value is determined for each node of the set of nodes, in each node of the set of nodes, the backoff value associated with a node being determined as a function of the specific value associated with that node.

In order to adjust the maximum size of the information sequences transmitted by a plurality of terminals in a network, according to a predetermined network protocol, between two subnetworks supporting different maximum sizes of information sequence: there is stored in an information base, for each of the terminals, an identifier for this terminal and the maximum size of the information sequences allowed by the network protocol for communicating with this terminal; the information base is updated from the analysis of any information sequence conveyed in one of the subnetworks; then, for each information sequence to be transmitted: the identifier of the destination terminal and the corresponding maximum size of the information sequences are read in the information base; the maximum size read is compared with the current maximum size allowed by the network protocol; and, if the maximum size read is less than the current maximum size, the current maximum size is adjusted by allocating to it the value of the maximum size read.

The invention relates to a method for acknowledging data received by a communication device, the data being received by data packets, with each packet comprising a plurality of data blocks. The communication device: determines (E503), for a packet, the number of data blocks whose data can be processed correctly, sends (E509, E510; E515) an acknowledgement for at least one data block in the packet if the number of data blocks whose data can be processed correctly is between a first and a second threshold, and sends (E504, E505, E511, E512, E515), for the data packet, a piece of information at packet level representing the number of data blocks whose data can be processed correctly if the number of data blocks whose data can be processed correctly is lower than the first threshold or higher than the second threshold.

The present invention relates to a method of synchronisation between communication networks exchanging information by frame of informations, each communication network having clock and the number of clock pulses is monitored by a counter. The synchronisation is made by reading information representing the counted clock pulses of the clock of the first network at the appearance of a reference event, inserting at least said information or calculated information on the basis of said information into the frame of information as the synchronisation information, transferring said frame of information from the first to the second network, reading information representing the number of counted clock pulse of the clock of the second network at the appearance of reference event, reading synchronisation information inserted in received frame of information from the first network, calculating a difference between information and synchronising the second network.

Method for managing a distribution of bandwidth in a communications network, corresponding computer-readable storage medium and slave node.A method is proposed for managing a distribution of bandwidth in a communications network by means of a slave node of the network, said network comprising a set of nodes.The slave node is such that it performs steps for: determining a coarse representation and a detailed representation of the distribution of the bandwidth in said network, as a function of a piece or pieces of information relative to conditions of transmission in said network and/or relative to applications needs of transmission; receiving a coarse reference representation of the distribution of bandwidth in said network, coming from a master node of said network; comparing said determined coarse representation and said reference coarse representation; should said coarse representations be identical, applying said determined detailed representation; if not, applying said coarse reference representation.
