A data processing method for processing data in an ad hoc radiocommunication network that comprises a set of radiocommunication stations each constituting a node of the ad hoc network, according to which: - at least one station executes a dynamic topology discovery function in accordance with a routing protocol that is operationally implemented in the ad hoc network, that comprises the sending from the station of a set of topology elements intended for updating the topology of the network; and - at least one application generates application related data intended to be transmitted by the said station to at least one other station of the network, the said method being characterised in that it comprises the following steps: - reception of the application related data generated by the application, by an electronic data processing block of the station, and translation by the said electronic data processing block, of the said application related data into fictitious topology related elements in accordance with a database of predetermined rules that ensure the mapping of the application related data with the corresponding fictitious topology related elements; - insertion of the fictitious topology related elements into the said set of topology related elements, the said set of topology related elements transmitted by the station comprising the said inserted fictitious topology related elements, a fictitious element as inserted being an element from among a fictitious node, a fictitious communication link, a fictitious communication network, a fictitious modification of at least one characteristic feature of a real topology element from among a node, a link and a communication network the application data being of the following types: - a state and a location of an application service; - a mode of operation of the application; - a membership of a node in a group of nodes; - a role of the nodes of the network in the operational deployment of an application service; or - an access to a resource that is not on the network but for which one or more nodes of the network are gateways to be used for accessing these resources from the nodes of the network. - at least one station executes a dynamic topology discovery function in accordance with a routing protocol that is operationally implemented in the ad hoc network, that comprises the sending from the station of a set of topology elements intended for updating the topology of the network; and - at least one application generates application related data intended to be transmitted by the said station to at least one other station of the network, - reception of the application related data generated by the application, by an electronic data processing block of the station, and translation by the said electronic data processing block, of the said application related data into fictitious topology related elements in accordance with a database of predetermined rules that ensure the mapping of the application related data with the corresponding fictitious topology related elements; - insertion of the fictitious topology related elements into the said set of topology related elements, the said set of topology related elements transmitted by the station comprising the said inserted fictitious topology related elements, a fictitious element as inserted being an element from among a fictitious node, a fictitious communication link, a fictitious communication network, a fictitious modification of at least one characteristic feature of a real topology element from among a node, a link and a communication network the application data being of the following types: - a state and a location of an application service; - a mode of operation of the application; - a membership of a node in a group of nodes; - a role of the nodes of the network in the operational deployment of an application service; or - an access to a resource that is not on the network but for which one or more nodes of the network are gateways to be used for accessing these resources from the nodes of the network. - a state and a location of an application service; - a mode of operation of the application; - a membership of a node in a group of nodes; - a role of the nodes of the network in the operational deployment of an application service; or - an access to a resource that is not on the network but for which one or more nodes of the network are gateways to be used for accessing these resources from the nodes of the network.
