One embodiment relates to data routing using first and second pieces of IP type equipment, the second piece of equipment being suitable for communicating with a management node of a sensor network. The sensors may have respective IP addresses that are generated by said management node, the node also having a function of routing data in the sensor network. The method includes, in a router, generating an address for the second piece of equipment, verifying the availability of the address in the sensor network from the management node, and if the address is available, requesting the management node to add the second piece of equipment in the sensor network.
