On-demand medium to low transmission power channel switching in computer networks
First Claim
1. A method, comprising:
- in a low power and lossy network (LLN) comprising a plurality of devices, determining, by a sender device, that data for transmission to a receiver device is capable of being transmitted via a low-power channel;
determining, by the sender device, if the receiver device is listening on a low-power channel hopping schedule sufficient to transmit the data to the receiver device;
in response to determining that the receiver device is not listening on a low-power channel hopping schedule sufficient to transmit the data to the receiver device, transmitting, by the sender device, a control message to the receiver device via a channel-hopping schedule of the receiver device, wherein the control message instructs the receiver device to listen on the low-power channel hopping sequence; and
transmitting, by the sender device, the data to the receiver device via the low-power channel hopping schedule.

Abstract
In a multiple interface, low power and lossy network comprising a plurality of nodes, a low transmission power and medium transmission power topology are defined for the network and a channel-hopping schedule is defined for the devices operating in each topology. A sender determines that data is capable of being transmitted via a link on the low transmission power topology. The sender determines the transmission parameters for the transmission of the data over the link on the low transmission power topology and determines a low transmission power channel for transmission of the data. The sender transmits the determined channel and the transmission parameters to the receiver. The sender transmits the data via the determined channel in the low transmission power topology.

10. An apparatus, comprising:
-
one or more network interfaces to communicate with a low power and lossy network (LLN); a processor coupled to the network interfaces and adapted to execute one or more processes; and a memory configured to store a process executable by the processor, the process when executed operable to; determine that data for transmission to a receiver device is capable of being transmitted via a low-power channel; determine if the receiver device is listening on a low-power channel hopping schedule sufficient to transmit the data to the receiver device; transmit, in response to determining that the receiver device is not listing on a low-power channel sufficient to transmit the data to the receiver device, a control message to the receiver device via a channel-hopping schedule of the receiver device, wherein the control message instructs the receiver device to listen on the low-power channel hopping sequence; receive an acknowledgement message from the receiver device, the acknowledgement message indicating the receiver device is now listening on the low-power channel; and transmit the data to the receiver device via the low-power channel hopping schedule. - View Dependent Claims (11, 12, 13, 14, 15)

16. A tangible, non-transitory, computer-readable media having software encoded thereon, the software when executed by a processor operable to:
-
in a low power and lossy network (LLN) comprising a plurality of nodes, determine that data for a receiver device is capable of being transmitted via a low-power channel; determine if the receiver device is listening on a low-power channel hopping schedule sufficient to transmit the data to the receiver device; transmit, in response to determining that the receiver device is not listing on a low-power channel sufficient to transmit the data to the receiver device, a control message to the receiver device via a channel-hopping schedule of the receiver device, wherein the control message instructs the receiver device to listen on the low-power channel hopping sequence; receive an acknowledgement message from the receiver device, the acknowledgement message indicating the receiver device is now listening on the low-power channel; and transmit the data to the receiver device via the low-power channel hopping schedule. - View Dependent Claims (17, 18, 19, 20)
