Abstract: In a wireless mesh network, a battery operated node can select a parent node via which messages are routed to further nodes. The parent node can initially be selected based on signal strength. The node receives acknowledgements for messages sent, if they arrive. The node calculates a reliability indicator of the parent node based on the number of messages for which an acknowledgement has been received. If the reliability indicator exceeds a predetermined threshold the node selects a new parent node, based on second selection criteria. For example, the node with the next greatest signal strength.

Abstract: A method and apparatus for controlling distribution of illumination information in an illumination system, wherein illumination settings to be sent for storing at one or more luminaires are determined based on one or more priority metrics. Priority metrics may be based on previous usage of an illumination setting, or the content of an illumination setting for example. The determination and sending can be commenced by a trigger such as a time of day or a user input, and evaluation of priority metrics can be performed to so that illumination settings are stored intelligently based on a user profile, preference or schedule.

Abstract: This disclosure relates to communicating on a wireless channel in the presence of an interference source. A receiver accesses the channel to perform a sequence of energy detections. The interference source is modelled as cyclically transitioning into and out of an inactive state and as cyclically transitioning, when out of the inactive state, between a first active state, in which the interference source is active and creating interference on the channel, and a second active state, in which the interference source is active but creating a substantially lower level of interference on the channel. Based on the sequence of energy detections, large and small time scale metrics are determined. Transmission of data by a transmitter is in dependence on the estimated metrics.

Abstract: The disclosure describes is a channel switching strategy and corresponding protocol for a mesh network which comprises a segment controller (SC) and a large number of outdoor luminaire controllers (OLCs) or other network nodes. A channel switching process is initiated and managed by the SC which transmits a channel switching command to all nodes in the system. Following the actual channel switch, the SC delegate's responsibility to request an orphan node to switch to the new channel to a selected delegate node which is a neighbor node of the orphan node. The selection of the delegate node may be based on a prioritization. When an OLC does not receive any messages for a specified, prolonged period of time, it may scan available frequency bands to find the (new) channel in which the networked system operates at that time.
