Reliable reporting in wireless mesh network

A device arranged for operating as a node in a wireless mesh network, the device comprising:

• an interface arranged for communicating with the wireless mesh network,
• a processor arranged for sending and receiving messages via the interface, wherein the processor is further arranged for:
• selecting, based on first selection criteria, a parent node through which the device will communicate with one or more further nodes in the wireless mesh network, wherein the first selection criteria comprise signal strength, subsequently
• sending one or more messages destined to at least one of the one or more further nodes in the wireless mesh network via the selected parent node, subsequently
• calculating a reliability indicator of the parent node by receiving from the parent node acknowledgements for which an acknowledgement has been received from the one or more further nodes said messages were destined for, and subsequently
• selecting a new parent node, based on second selection criteria, when the reliability indicator exceeds a predetermined threshold, wherein the second selection criteria comprise signal strength;
• wherein the processor selecting a new parent node is further conditional based on one or more of:
• the time passed since the last selection of a new parent node, the number of times a new parent node has been selected in a predetermined time period, and the number of nodes capable of operating as a parent node from which a new parent node can be selected.
