Title: RELAYING MESSAGES OF UNREACHABLE NODES VIA THE NEIGHBOR NETWORK TO TARGET MESH NETWORK
Abstract:
A method of relaying messages to a node of a target wireless mesh network that is currently unreachable within the target network, wherein the target network and a neighbouring wireless mesh network are connected to an intermediary network via respective gateways, the gateways being registered with a portal system of the intermediary network, the method comprising, at a relaying node of the neighbouring network: receiving from the unreachable node of the target network, via a wireless link, a discovery message broadcast by the unreachable node, thereby detecting the unreachable node; causing a notification request to be transmitted from the registered neighbouring network gateway to the portal system via the intermediary network, the notification request comprising an identifier of the target network gateway and an identifier of the unreachable node, thereby causing the portal system to transmit a notification of said detection to the registered target network gateway; receiving from the portal system, via the intermediary network and the neighbouring network gateway, at least one message generated at the target network to be relayed to the unreachable node of the target network; and relaying the at least one message from the relaying node of the neighbouring network, via the wireless link, to the unreachable node of the target network.
