摘要： 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.

摘要： A controller for controlling a lighting system, the controller comprising: an interface arranged to communicate with one or more luminaires at a location to be illuminated; a memory arranged to store information, the information comprising a first illumination status of the location, and information of a first command causing the location to adopt the first illumination status; the interface further arranged to receive a second command comprising an instruction for the at least one luminaire to illuminate the location in accordance with a second illumination status which differs from the first illumination status; and a processor configured to determine whether to execute the second command based upon a comparison between a value associated with the first command and a value associated with the second command, the processor configured to calculate the value associated with the first command based upon a priority level value of the first command and a relevance factor associated with the first command, at a time of receiving the second command; and the processor configured to calculate the value associated with the second command based upon a priority level value of the second command.
