    Abstract: In one embodiment, a local node in a communication network determines a set of its neighbor nodes, and determines a respective occurrence frequency at which each particular neighbor node is to be probed based on a rate of change in distance between the local node and the particular neighbor node. The local node may then probe each particular neighbor node according to the respective occurrence frequency to determine the rate of change in distance between the local node and each particular neighbor node, and one or more routing metrics for reaching each particular neighbor node. As such, the local node may select, based on the probing, a suitable preferred next-hop node of the set of neighbor nodes for a corresponding routing topology.

    Abstract: In one embodiment, a router operating in a hierarchically routed computer network may receive collected data from one or more hierarchically lower devices in the network (e.g., hierarchically lower sensors or routers). The collected data may then be converted to aggregated metadata according to a dynamic schema, and the aggregated metadata is stored at the router. The aggregated metadata may also be transmitted to one or more hierarchically higher routers in the network. Queries may then be served by the router based on the aggregated metadata, accordingly.

    Abstract: In one embodiment, an energy-harvesting communication device of a communication network accumulates energy, e.g., electromagnetic energy. Upon detecting that the accumulated energy surpasses a sufficient threshold, the communication device may transmit a message into the communication network using the accumulated energy as an unreliable and unsynchronized broadcast transmission to any available receiver within the communication network.

    Abstract: In one embodiment, a device (e.g., a transmitter) determines a level of error protection of each bit position within symbols of a particular constellation map used for modulation-based communication, and also determines priority levels of application data bits to be placed into a communication frame. Application data bits may then be placed into symbols of the communication frame, where higher priority application data bits are placed into bit positions with greater or equal levels of protection than bit positions into which lower priority application data bits are placed. The communication frame may then be transmitted to one or more receivers with an indication of how to decode the placement of the application data bits within the symbols. In another embodiment, the particular constellation map may be dynamically selected from a plurality of available constellation maps, such as based on communication channel conditions and/or applications generating the data.

    Abstract: In one embodiment, a communication device of a communication network determines its available power level, and also estimates a power requirement to receive an expected transmission from a transmitter of the communication network. By determining whether the available power level is sufficient for the estimated power requirement, the device may correspondingly provide feedback to the transmitter regarding whether the available power level is sufficient for the estimated power requirement (e.g., if insufficient, either ignoring the transmission or returning an explicit reply). In another embodiment, further power conservation may be afforded through a radio-triggered wake-up mechanism.
