A method in an ad hoc network, preferably operated under a link state routing protocol such as OLSRv2, 100 is disclosed. It comprises: a node 3 advertising a theoretical destination it is not currently connected to as part of a theoretical route; allocating to the theoretical destination a special metric value that gives a reduced likelihood of selection as a suitable route compared to conventionally available routes; determining that a message from a further node 1, 2 is to be transmitted via the theoretical route; the node 3 receiving the message from the further node 1, 2 when the node 3 is at a first location 31 and storing the message; the node 3 moving to a second location 32 thereby transforming the theoretical route into a new real route; and the node 3 transmitting the message to a second further node as part of the new real route. The special metric value is preferably higher than that of conventionally available routes, and such that routes involving the theoretical destination will be ones of last resort. Some or all of the nodes in the network may be unmanned vehicles, preferably air vehicles. Apparatus implementing the method is also disclosed. |
