Abstract: A method and system is disclosed for allocating resources in a communication network including several nodes capable of transmitting and receiving data and a central node capable of allocating resources. At least one node transmits one or more requests (Rnqt) to the central node with each request (Rnqt) being associated with a requirement (qi). The central node allocates a lifetime (?tqi) to each request (Rnqt) according to the requirement (qi) of the request. Each request (Rnqt) is scheduled in a queue according to the lifetime (?tqi) and the moment of receipt (tR) of the request.
