Abstract: A node for a multi-hop communication network may include a wireless communication interface, configured to exchange data with the multi-hop communication network. The node moreover includes a processing unit, configured to drive the operation of the node as a function of the commands received via the wireless communication interface, and a memory storing a firmware for the processing unit. The node is configured to receive, via the wireless communication interface, an updated firmware, and to store the updated firmware into the memory. Moreover, the node is configured to detect, via the wireless communication interface, other nodes that are in the vicinity of the node, and to send (1010) the firmware stored in the memory to one or more of said nodes.
