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.

Abstract: Utilizing multiple network interfaces when sending data and acknowledgement packages comprises, in a low power and lossy network (LLN) or other network, a sender device comprises two or more network interfaces for communicating with one or more recipient devices. The sender device assesses the transmission capabilities of the network interfaces to determine data rates available for each interface. The sender device specifies which network interface will be used to transfer data and which network interface will be used to receive an acknowledgement from the recipient device. The sender device selects the network interface with the larger data capacity for transmitting a data packet and the network interface with the smaller data capacity for receiving an acknowledgement. The data transmission and the acknowledgement transmission may be transmitted simultaneously. The recipient device uses transmission parameters received from the sender device to determine the data rate with which to transmit the acknowledgement.

Abstract: In one embodiment, a primary node in a shared-media communication network is selected by a node toward a destination. In response to determining the primary node, the node determines a frequency-hopping schedule of the primary node. One or more backup nodes for the primary nodes are then determined based on a frequency-hopping schedule diversity between the primary node and the one or more backup nodes.

Abstract: In one embodiment, a node may discover the density of neighboring nodes in a frequency-hopping communication network. In response to identifying a power outage condition, the node may also dynamically determine an initial power outage notification (PON) transmission protocol based on the density of neighboring nodes. The node may then communicate a first PON to a plurality of neighboring nodes according to the initial PON transmission protocol.

Abstract: In one embodiment, a nodal device receives information from each of its neighboring nodes in a network. The information identifies a link quality between the nodal device and each of its neighboring nodes. The link quality information is stored in one or more bloom filters in the nodal device such that a table having a compressed format is provided in the bloom filter. The table includes probabilistic identifiers to identify link quality between the nodal device and each of its neighboring nodes.
