Selection of dynamic relays for cooperative communications in a mobile network

摘要

The invention relates to the selection of at least one dynamic node, in a mobile network, as a candidate for relaying a data communication signal between a transmitting entity and a receiving entity of the network. In terms of the invention: at least one first area around at least one first entity among the transmitting and receiving entities is defined, beyond which a data communication signal is attenuated beyond a first predetermined threshold; and the selection of nodes as possible candidates for relaying the communication signal on the basis of the definition of the first area is limited.

1. A method for selecting at least one dynamic node, within a mobile network, as a candidate for relaying a data communication signal between a transmitter entity and a receiver entity of the network,
comprising the steps:
determining at least a first set of nodes of the network such that a signal communicated between one of the nodes of the first set and at least a first entity from between said transmitter and receiver entities undergoes an attenuation lower than a first predetermined threshold,limiting the selection of nodes as possible candidates for relaying the communication signal according to the content of said first set,
wherein the method further comprises the steps:determining a signal attenuation between the transmitter entity and receiver entity,determining a second set of nodes such that a signal communicated between a node of the second set and the second entity from between said transmitter and receiver entities undergoes an attenuation lower than a threshold corresponding to said signal attenuation between the transmitter entity and the receiver entity,determining an intersection between the first set and a second set of nodes,limiting further the selection of nodes as possible candidates for relaying the communication signal to the nodes of said intersection of first and second sets, andestablishing data communication between said transmitter and receiver entities using at least one relay node, said at least one relay node being limited to the nodes of said intersection of sets.
