A resource reservation method respecting end-to-end bit rate and/or latency constraints with guaranteed service in terms of minimum bit rate Dmin and maximum access time Amax at N nodes of a radio network using time slots Di, a time slot being associated with a basic bit rate Deli for sending and transmitting data, each node of the network comprising a transport layer and a MAC network access layer, said method comprising at least the following steps: • sending, by a transport layer of a node of the radio network, a reservation request to the MAC layer of said node; • sending, from a source node, a resource reservation request in a format of Path and Resv messages of a RSVP reservation protocol, comprising: - a field Ts corresponding to a maximum duration of a time slot observed on a current path in the Adspec reservation request of the Path message, transmitted from the source node, the resource reservation request indicating a maximum bandwidth for the current path; - a field n over a number of radio nodes crossed in an object of the Path message, and - a fields of a maximum waiting time for a time slot in a Rspec object of the Resv message corresponding to a response to the reservation request sent by the recipient to the source node, the Rspec object indicating a bandwidth to be reserved for a data stream; • Reservieren, durch die MAC-Schicht des Knotens, einer Anzahl von Zeitschlitzen Di, die notwendig sind, um eine in der Reservierungsanfrage angemeldete Dienstgarantie zu erfüllen, wobei jeder Zeitschlitz Di durch einen elementaren Durchsatz Deli charakterisiert ist.reserving, by the MAC layer of said node, a number of time slots Di needed to satisfy a service guarantee recorded in the reservation request, each slot Di being characterised by a basic bit rate Deli. • sending, by a transport layer of a node of the radio network, a reservation request to the MAC layer of said node; • sending, from a source node, a resource reservation request in a format of Path and Resv messages of a RSVP reservation protocol, comprising: - a field Ts corresponding to a maximum duration of a time slot observed on a current path in the Adspec reservation request of the Path message, transmitted from the source node, the resource reservation request indicating a maximum bandwidth for the current path; - a field n over a number of radio nodes crossed in an object of the Path message, and - a fields of a maximum waiting time for a time slot in a Rspec object of the Resv message corresponding to a response to the reservation request sent by the recipient to the source node, the Rspec object indicating a bandwidth to be reserved for a data stream; - a field Ts corresponding to a maximum duration of a time slot observed on a current path in the Adspec reservation request of the Path message, transmitted from the source node, the resource reservation request indicating a maximum bandwidth for the current path; - a field n over a number of radio nodes crossed in an object of the Path message, and - a fields of a maximum waiting time for a time slot in a Rspec object of the Resv message corresponding to a response to the reservation request sent by the recipient to the source node, the Rspec object indicating a bandwidth to be reserved for a data stream; • Reservieren, durch die MAC-Schicht des Knotens, einer Anzahl von Zeitschlitzen Di, die notwendig sind, um eine in der Reservierungsanfrage angemeldete Dienstgarantie zu erfüllen, wobei jeder Zeitschlitz Di durch einen elementaren Durchsatz Deli charakterisiert ist.reserving, by the MAC layer of said node, a number of time slots Di needed to satisfy a service guarantee recorded in the reservation request, each slot Di being characterised by a basic bit rate Deli.
