Abstract

Devices and computer-implemented methods for controlling data communication to one or more devices in a network, e.g., a mesh network. The methods include a device broadcasting data requested by a first device, and a second device eavesdropping on the broadcast of the data in order to capture the data and to storing the captured data if the data is appropriate for the second device.

Claims

1. A computer-implemented method for controlling data communication for one or more devices connected in a network, comprising:

a first device receiving a request for data from a second device; and

the first device broadcasting to the network the data that was requested by the second device.

2. The computer-implemented method according to claim 1, further comprising:

a third device eavesdropping on the broadcasting by the first device;

the third device receiving the data;

the third device having a processor that executes a computer-executable instructions and determining whether the data is appropriate for the third device; and

the third device storing the data to a non-transitory computer-readable memory of the third device when the third device has determined that the data is appropriate for the third device.

3. The computer-implemented method according to claim 1, further comprising:

the second device sending the request of the data to the first device via unicasting.

4. The computer-implemented method according to claim 1, further comprising:

the second device broadcasting the request of the data to the network.

5. A non-transitory computer-readable memory including computer-readable instructions for controlling data communication for one or more devices in a network, comprising instructions stored thereon, that when executed on a processor, performs the method in claim 1.

6. A non-transitory computer-readable memory including computer-readable instructions for controlling data communication for one or more devices in a network, comprising instructions stored thereon, that when executed on a processor, performs the method in claim 2.

7. A non-transitory computer-readable memory including computer-readable instructions for controlling data communication for one or more devices in a network, comprising instructions stored thereon, that when executed on a processor, performs the method in claim 3.

8. A non-transitory computer-readable memory including computer-readable instructions for controlling data communication for one or more devices in a network, comprising instructions stored thereon, that when executed on a processor, performs the method in claim 4.

9. A network system, comprising:

one or more node devices connected via a network;

a controller device configured for communicating with the one or more node devices via the network, wherein each of the one or more node devices comprises a processor, a non-transitory computer-readable memory, and a network interface, wherein the processor includes a computer-executable instructions that when executed by the processor transmits a request for data via the network interface to the controller device, and the computer-executable instructions when executed by the processor broadcasts the data to the network.

10. The network system according to claim 9, wherein at least one of the one or more node devices which did not communicate the request for the data to the controller device further includes a computer-executable instructions that when executed by the processor performs the steps of:

eavesdropping the data broadcasted by the controller device; and

storing the data broadcasted by the controller device to the non-transitory computer-readable memory.

11. A communication method between computer devices in a network, comprising:

a first device transmitting a request for data to a controller device;

the controller device receiving the request from the first device;

the controller device broadcasting the data requested by the first device to the network;

one or more other devices other than the first device receiving the data via broadcast from the controller device; and

each of the one or more other devices storing the data to a respective non-transitory computer-readable memory.

12. The communication method according to claim 11, further comprising:

the one or more other devices transmitting another request for another data to the controller device;

the controller device receiving the another request from the one or more other devices;

the controller device broadcasting the another data requested by the one or more other devices to the network;

the first device receiving the another data via broadcast from the controller device; and

the first device storing the another data to a non-transitory computer-readable memory of the first device.

13. The communication method according to claim 11, further comprising:

the first device receiving the data via broadcast from the controller device; and

the first device storing the data to a non-transitory computer-readable memory of the first device.
