摘要:
A method for a node to transmit data in a telecommunications network is disclosed. In one method aspect, it comprises, selecting a time slot j in a window having a plurality of time slots and preceding a transmission period, listening to time slots preceding the time slot j, wherein the transmission period presents a plurality of transmission channels. Furthermore, the method comprises counting a number of time-slot transmissions during the time slots preceding the time slot j wherein when the number of time-slot transmissions is greater than a threshold, the data transmission is postponed or cancelled. Furthermore, when the number of time-slot transmissions is less than or equal to the threshold, a transmission is made during the time slot j, and one of the transmission channels is determined as a function of said number of time-slot transmissions.

摘要:
A system and method organize a network of communicating objects in at least one partition comprising a plurality of communication cells respectively covered by a plurality of leader nodes, the network having a set of allocatable addresses split into a plurality of address pools distributively managed by the leader nodes. Upon a new node arrival, phase (a) and possibly phase (b) are executed. During phase (a), if the new node detects a leader node, it allocates an address from its managed address pool and the new node assumes a member node roll in the leader node cell. If the new node does not detect any leader node in its vicinity, it goes on to the phase (b), wherein, if the new node detects a first cell member node, it assumes the role of leader covering a second cell, obtains an available pool of managed addresses and is allocated one of the obtained addresses.
