摘要： In one embodiment, a particular node in a shared media computer network may determine a set of network parameters for the network, and a timing of super-frames in the network, each super-frame having one or more frames, each frame divided into a plurality of timeslots. In addition, the particular node computes a discovery scheduling function using its own identification to determine in which particular timeslot of the frames to transmit a network discovery packet. Accordingly, the particular node may transmit the network discovery packet in the particular timeslot of the frames. In an additional or alternative embodiment, the particular node may receive a network discovery request from a requesting node. In response, the particular node determines whether it is free to reply to the network discovery request based on parameters in the network discovery request, and if free to reply, may transmit a network discovery packet to the requesting node.

摘要： In one embodiment, a data aggregator discovery (DAD) message may be distributed by an associated data aggregator, the DAD message identifying the initiating data aggregator, and comprising a recorded route taken from the data aggregator to a receiving particular node as well as a total path cost for the particular node to reach a root node of the DAG through the recorded route and via the data aggregator. The receiving particular node determines a path cost increase (PCI) associated with use of the data aggregator based on the total path cost as compared to a DAG-based path cost for the particular node to reach the root node via the DAG. If the PCI is below a configured threshold, the particular node may redirect traffic to the data aggregator as source-routed traffic according to the recorded route. The traffic may then be aggregated by the data aggregator, accordingly.
摘要翻译：在一个实施例中，数据聚合器发现（DAD）消息可以由相关联的数据聚合器分发，DAD消息标识发起数据聚合器，并且包括从数据聚合器到接收特定节点的记录路由以及总数特定节点通过记录的路由并经由数据聚合器到达DAG的根节点的路径开销。与特定节点通过DAG到达根节点的基于DAG的路径开销相比，接收特定节点基于总路径开销来确定与数据聚合器的使用相关联的路径成本增加（PCI）。如果PCI低于配置的阈值，则特定节点可以根据记录的路由将流量重定向为数据聚合器作为源路由业务。因此，流量可以由数据聚合器进行聚合。

摘要： In one embodiment, hidden neighbor relationships are identified based on received neighbor information from a plurality of nodes in a communication network. Based on determining a number of hidden neighbors for a particular node at various node parameters, a cost function associated with the particular node may be determined and utilized. In another embodiment, a number of hidden nodes of the particular node is determined across a range of transmission powers, and a delay associated with the particular node reaching a root node in the network across the range of transmission powers is also determined based on the neighbor nodes reachable at respective transmission powers. A tradeoff is determined across the range of transmission powers between the number of hidden nodes and the delay, and then the transmission power of the particular node can be set based on an acceptable determined tradeoff.

摘要： In one embodiment, a node may determine a trigger for establishing transmission priority on a path through a shared-media communication network for priority traffic to a particular node. As such, the node may generate a path clear message (PCM) that would instruct one or more receiving nodes along the path to suspend transmission for traffic other than the priority traffic for a specified duration, and also to transmit a local non-repeated distributed message to one or more neighbor nodes of each respective receiving node, the local non-repeated distributed message to instruct the neighbor nodes to suspend transmission for the specified duration. After transmitting the PCM along the path to the particular node to establish the transmission priority for the priority traffic along the path through the shared-media network, the priority traffic may be transmitted to the particular node along the path during the transmission priority.

摘要： In one embodiment, a particular node in a computer network, that is, one receiving electrical power from a grid source, may determine routing metrics to a plurality of neighbor nodes of the particular node in the computer network. In addition, the node also determines power grid connectivity of the plurality of neighbor nodes. Traffic may be routed from the particular node to one or more select neighbor nodes having preferred routing metrics, until a power outage condition at the particular node is detected, at which time the traffic (e.g., last gasp messages) may be routed from the particular node to one or more select neighbor nodes having diverse power grid connectivity from the particular node. In this manner, traffic may be routed via a device that is not also experiencing the power outage condition.
