INTERLEAVING LOW TRANSMISSION POWER AND MEDIUM TRANSMISSION POWER CHANNELS IN COMPUTER NETWORKS
First Claim
1. A method, comprising:
- in a low power and lossy network (LLN) comprising a plurality of computing devices, generating a mixed channel-hopping sequence comprising an interleaved low-power channel hopping sequence and a medium-power channel hopping sequence, such that a single device in the network may allow neighboring devices in the network to use both low-power and medium-power channels to communicate with the single device.

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.
