A method of resource reservation with service guarantee in terms of throughput and deadline at the level of the N nodes of a radio network using time slots to send and transmit data is disclosed, which implements a global reservation process in which a reservation message sent uses at least one of the following two parameters: the maximum deadline required to access the radio medium, the minimum throughput required in order to satisfy the service guarantee. A dynamic time slot allocation scheme is used that is defined in the following manner: the N nodes each include K slots, including a control slot, P elastic slots and (K-1-P) session slots, and the (K-1-P) session slots are amalgamated for the allocation of resources required by a node at a given instant.
