<p>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).</p> |
