    摘要： There is disclosed a method for distributing data across a network which comprises a plurality of nodes.
    The method includes a step of publishing the data, said step being performed by a node producing the data.
    The method includes a step of subscribing to the kind of the data, said step being performed by at least one node consuming the data.
    The data are conveyed from the producing node to the consuming nodes by use of the Source-Specific Multicast method even in case of only one consuming node, so as to limit data distribution between the nodes.
    Application : distribution of data in a wide area network, telephony and conferencing.

    摘要： There is disclosed an apparatus for emitting and receiving radio-frequency signals, the apparatus comprising a circuit to cancel interferences.
    It comprises means for transmitting at least one signal by virtue of an antenna, means for receiving signals by the same antenna and means for isolating the means for transmitting from the means for receiving.
    The apparatus comprises also:
    - means for tapping a first part of the signal to be transmitted;
    - means for controlling the amplitude and the phase of the first part of the signal;
    - means for introducing the first part of the signal in the means for receiving after said first part of the signal has been amplified and phase-shifted, such as to cancel in the means for receiving interferences due to portions of the signal that unwantedly have entered the means for receiving.

    摘要： The present invention relates to a method and concomitant system that selects a node to fulfill the role of a relay node in a wireless communication system. The method comprises at least the following steps:
    • determine the remaining battery energy level (202) of each node;
    • solve (313) a linear program maximizing the sum of times X u that each master-designed node u should remain the relay node under constraints depending at least on the transmit power needed by each node v when a node u is the relay node, on the message transmission rates of each node, and on said remaining battery energy levels ;
    • according to times X u found previously, select (314) the relay nodes.
    The invention applies to mobile radio networks, especially to Personal Mobile Radio networks (PMR).
