Method of reserving resources with guarantee of service at minimum bit rate Dmin and at maximum access time Amax at the level of the N nodes of a radio network using time slots Di each associated with an elementary bit rate DeIi so as to send and transmit data, a node of the network comprising a protocol layer and an MAC network access layer, characterized in that it comprises at least the following steps: for a given node (3i), the protocol layer (4i) of said node sends a reservation request to the MAC layer (5i) of said node, the source node (1) sending the data, introduces at the level of the format of the messages Path and Resv of the RSVP protocol: - a field Ts corresponding to the maximum duration of the time slot observed on the current path in the reservation request Adspec of the message Path, transmitted from the source node (1) to a destination (2), - a field n on the number of radio nodes traversed in the object of the message Path, - a field τ of maximum waiting delay of the time slot in the object Rspec of the message Resv corresponding to the response to the reservation request sent by the destination to the source node (1), - the MAC layer (5i) of said node (3i) reserves the number of time slots Di necessary for satisfying the guarantee of service inscribed in the reservation request. Application to the ad hoc radio network. |
