Abstract: A node having a multiple protocol receiver may listen to multiple links in parallel and determine a quality of links having multiple communication technologies between the node and multiple neighbor nodes. The multiple communication technologies may include radio frequency (RF) communication technologies and one or more power line communication (PLC) communication technologies. The node determines a link quality metric for each link associated with an optimum communication technology and data rate, and maintains availability information of neighbor nodes. The node may then route communications to neighbor nodes using the link quality metric and the availability information.

Abstract: In a wireless and/or power line communication (PLC) network environment, techniques for multicast of data and management of multicast groups assist in regulating bandwidth consumption and provision of desired multicast data. Nodes indicate interest in multicast groups by transmission of reports upstream. Report transmission may be suppressed to balance bandwidth with need for multicast data. Multicast data packets may be retransmitted downstream to fulfill requests indicated by the reports at a rate and/or frequency based on multicast packet duplication or redundancy. Information, such as broken links or “leave” packets, may indicate that one or more downstream nodes should be removed from a forwarding state. However such removal may impact other nodes. A query may be transmitted downstream, to determine if retransmission/forwarding of multicast retransmissions should continue. Query transmission may be based on a balance between query bandwidth consumption and the needs of downstream nodes.

Abstract: Disclosed are techniques to minimize the electricity consumption of battery powered devices during network communications and performance of other functions. Example techniques include efficiently discovering other mains powered and battery powered devices within communication range of the battery powered device. In another example, techniques enable a battery powered device to serve as a relay for one or more other battery powered devices. In another example, techniques ensure that transmissions to and/or from battery powered devices are delivered efficiently and with low latency. In yet another example, techniques determine whether and under what conditions a battery powered device should migrate from one network to another. In the event of migration, example techniques minimize battery consumption associated with the migration.

Abstract: Techniques for broadcasting data in a multi-channel network having a control channel and multiple data channels are described. A node wishing to broadcast data may determine a particular data channel from among the multiple data channels, a modulation technique, and a data rate to be utilized to broadcast the data. The broadcasting node may transmit a message over the control channel indicating that the data will be broadcast on the particular data channel using the modulation technique and at the determined data rate. The broadcasting node and a node wishing to receive the data may switch to the particular data channel. The broadcast node may broadcast the data over the particular data channel, while the receiving node may receive the data. After broadcasting the data or a predetermined time period has expired, the broadcasting node and receiving node may switch to the control channel.
