Abstract

A method for concerted synchronization of data across a wireless mesh network comprises transmission of a broadcast message to a target device via a predicted route that is capable of being acknowledged by at least one network device not on the predicted route. The data is assimilated from at least one network device, and is capable of addition to a broadcast message. In this way, it is possible to synchronize a plurality of network devices via one outgoing broadcast message and one incoming broadcast message.

Claims

1. A method for concerted synchronisation of data across a wireless mesh network arrangement, the wireless mesh network arrangement comprising a control panel and a plurality of network devices, the method comprising transmission of a broadcast message to a target device via a predicted route, whereby first network devices are on the predicted route and second network devices are off the predicted route wherein first network devices that are on the predicted route and second network devices that are off the predicted route are configured and arranged to acknowledge the broadcast message and configured and arranged to append data relating to the state and configuration of the respective network devices to a broadcast message, wherein the control panel is configured and arranged to collate and assimilate data received from the network devices, wherein the plurality of network devices is synchronised via one outgoing broadcast message and one incoming broadcast message.

2. A method for concerted synchronisation of data according to claim 1 wherein the method of data communication is capable of being applied to a battery operated wireless mesh network arrangement.

3. A method for concerted synchronisation of data according to claim 2 wherein the mesh network arrangement may comprise a control panel, a receiving device for receiving data from, for example, the control panel and/or other devices within the mesh network arrangement, and a plurality of network devices located with the mesh network, capable of data exchange and communication.

4. A method of concerted synchronisation of data according to claim 3 wherein the control panel is capable of receiving data from devices comprising the mesh network arrangement, such that it may be aware of each device'"'"'s status at a given time so that the control panel can identify any devices that may be required to transmit or receive data.

5. A method of concerted synchronisation of data according to claim 1 where the control panel is able to communicate collated data to devices within the mesh network, including but not limited to a receiving device.

6. A method of concerted synchronisation of data according to claim 1 wherein the receiving device is able to locate a specific target device within the mesh network arrangement, with which to communicate said data.

7. A method of concerted synchronisation of data according to claim 1 wherein the receiving device is capable of transmitting messages to devices within the mesh network, including but not limited to the control panel and remote network devices.

8. A method of concerted synchronisation of data according to claim 1 where in the receiving device is able to communicate with a target device either directly or via at least one intermediate network device.

9. A method of concerted synchronisation of data according to claim 1 wherein the receiving device is capable of transmitting a single message to a target device, via at least one intermediate device on a communication route.

10. A method of concerted synchronisation of data according to claim 2 where the control panel is able to communicate collated data to devices within the mesh network, including but not limited to a receiving device.

11. A method of concerted synchronisation of data according to claim 3 where the control panel is able to communicate collated data to devices within the mesh network, including but not limited to a receiving device.

12. A method of concerted synchronisation of data according to claim 4 where the control panel is able to communicate collated data to devices within the mesh network, including but not limited to a receiving device.

13. A method of concerted synchronisation of data according to claim 1 where the control panel is able to communicate collated data to devices within the mesh network, including but not limited to a receiving device.
