A dedicated method for determining peers located close to another peer, each peer having at least one communication device connected to a communication node of a communication network including multiple communication nodes, of which some have a known fixed position and are known as “landmarks”. This method consists in, upon detection of a new peer, i) in determining in the communication network the closest landmark to the new peer, then ii) in determining from among the multiple nodes known as intermediary nodes that define the path linking this new peer to the pre-determined landmark, and iii) in determining a group of peers located close to the new peer as a function of at least the pre-determined path definition and the definitions of the paths linking other peers to at least the pre-determined landmark.
Method for determining peers located close to another peer, each peer having at least one item of communication equipment connected to a communication node of a communication network comprising multiple communication nodes of which some have a known fixed position and are known as “landmarks”, consisting, in the case of detection of a new peer in determining within said network the landmark that is closest to said new peer, then ii) in determining from among said multiple nodes known as intermediary nodes that define a path connecting said new peer to said determined landmark, and iii) in determining a group of peers located close to said new peer according to at least the definition of said path and of path definitions connecting other peers, connected to said network, to at least said determined landmark.
Server (SR) for a communication network to which are connected items of communication equipment of peers and comprising multiple communication nodes of which some have a known fixed position and are known as “landmarks”, wherein it is arranged, in the case of detection of a new peer, to determine a group of peers located close to said new peer according at least to the knowledge i) of nodes of said multiple nodes, known as intermediary nodes, that define a path connecting said new peer to the landmark that is closest to said new peer, and ii) intermediary nodes of said multiple nodes that define paths connecting other peers, connected to said network, to at least said landmark that is closest to said new peer.
Analysis device for an item of communication equipment of a peer connected to a communication node of a communication network comprising multiple communication nodes some of which have a known fixed position and are known as “landmarks”, wherein it is adapted i) to determine within said network the landmark that is closest to its peer communication equipment, then ii) to determine among said multiple nodes the nodes known as intermediary nodes that define a path connecting said peer communication equipment to said determined landmark.
