A wireless node (3) is for use in a wireless mesh network (i) in which nodes (2.3) receive and transmit routing broadcasts (5) to acquire routing information (6). The node is configured to transmit a routing broadcast only by retransmitting a routing broadcast received from another node. Within the network, some nodes are of a first type (2) and others of a second type (3). The first type of node is able to generate an initial routing broadcast and transmit it to another node. The second type of node is only able to rebroadcast a routing broadcast it has received from another node. This allows nodes within the network to obtain routing information. while reducing network overhead when compared to a wireless network where any nodes may initiate a routing broadcast. The routing broadcast may further include payload data, further reducing network resource overheads. |
