Abstract: A method for associating user equipment with base stations of a cellular network, in particular of a heterogeneous network such as a 5G network, uses a multi-agent reinforcement learning (MARL) algorithm. When a user equipment enters the network, the agent associated with this equipment downloads the instance of an association meta model to a coordinating unit, pre-trained by means of reinforcement learning. The agent subsequently constructs a local observation vector, comprising observables relating to the user equipment, and a global observation vector, including observables relating to the environment of this equipment. The local and global observation vectors are projected into the same reference space, the concatenation of the vectors thus projected encoding the state of the agent. It deduces from the model and from this state, an association decision. The model is updated according to a policy gradient method to consider evolution of the environment of the user.

Abstract: The present invention relates to an asynchronous communication method in a wireless sensor network comprising a tree structure. For each node of the network, the communication is organized as a sequence of time frames, each frame including a listening phase possibly followed by a receiving phase and/or a transmitting phase. The method, of the preamble sampling type, enables a node to make a time appointment to its child node to transmit them a time window allocation message, each child node then transmitting at least one data packet in the window it has been allocated to. By minimizing the collision risk between packets and by maximizing the time during which the sensors go to sleep, the communication method both reduces the latency and the consumption within the network.
