摘要： In one embodiment, a clustering device may determine one or more sensor clusters having a plurality of sensor devices that report similar data of a same data type in a sensor network. Accordingly, the clustering device may select a subset of the sensor devices in each respective sensor cluster as one or more representative devices, such that a sensor sink obtains data from only the representative devices.

摘要： In one embodiment, a sensor device in a network detects an alarm condition. The sensor device generates an alarm message based on the detected alarm condition and waits for a delay whose length is inversely proportional to a distance between the sensor device and a downstream destination device for which the alarm message is destined. During the delay, the sensor device receives one or more additional alarm messages from one or more upstream sensor devices. The sensor device coalesces the one or more received alarm messages from the one or more upstream sensor devices with the alarm message generated at the sensor device, to form a coalesced alarm message, and transmits the coalesced alarm message downstream towards the downstream destination device, after expiration of the delay.

摘要： In one embodiment, one or more routing trees may be determined based on corresponding root nodes to reach a particular receiving node in a computer network. A delay value may be calculated at each node of the routing tree, the delay value inversely proportional to a distance between each respective node and the root node of the tree. Upon detecting a trigger at a particular node of the tree to transmit a stormed message to the particular receiving node (e.g., an alarm), the particular node may initiate a timer to count down the delay value in order to receive any upstream node stormed messages prior to expiration of the timer. The particular node may then coalesce the upstream node stormed messages with the stormed message of the particular node, and may transmit the coalesced stormed message downstream along the tree toward the particular receiving node upon expiration of the timer.
摘要翻译：在一个实施例中，可以基于对应的根节点确定一个或多个路由树，以到达计算机网络中的特定接收节点。可以在路由树的每个节点处计算延迟值，延迟值与每个相应节点与树的根节点之间的距离成反比。在检测到树的特定节点处的触发以将特定接收节点（例如，报警）发送冲击的消息时，特定节点可以启动定时器以对延迟值进行倒计数以便接收任何上游节点冲击的消息在定时器到期之前。然后，特定节点可以与特定节点的冲击消息合并上游节点冲击的消息，并且可以在定时器到期时沿着树向下向特定接收节点发送合并的风暴消息。

摘要： In one embodiment, a node in a computer network may receive data of a particular type at a first frequency (e.g., a sensor in a sensor network), and may correspondingly determine whether there is at least one interested subscriber for the data of the particular type, where the interested subscriber desires the data at a second frequency. If there is an interested subscriber, buffered data publishing may be dynamically activated at the node in response to a ratio between the second and first frequencies being less than a configured threshold. In particular, buffered data publishing comprises buffering the received data and transmitting a latest received data to the interested subscriber at the second frequency.

摘要： In one embodiment, a reactive routing computer network may be partitioned into diverse logical topologies, and a source node may transmit route request (RREQ) messages toward a destination node on each logical topology. In response, the source node may receive route reply (RREP) messages indicating routes to the destination node in each logical topology. The source node may thus select a route for each logical topology to reach the destination node, accordingly. In another embodiment, if partitioned logical topologies do not produce two or more routes or as a standalone embodiment, the source node may transmit RREQ messages toward the destination node without any corresponding logical topology. The destination node receives RREQ messages, and two or more routes from the source node to the destination node may be determined (e.g., by the destination or source node) based on the received RREQ messages at the destination node and path selection criteria.
摘要翻译：在一个实施例中，可以将反应性路由计算机网络划分成不同的逻辑拓扑，并且源节点可以向每个逻辑拓扑上的目的地节点发送路由请求（RREQ）消息。作为响应，源节点可以在每个逻辑拓扑中接收指示到目的地节点的路由的路由回复（RREP）消息。因此，源节点可以相应地为每个逻辑拓扑选择到达目的地节点的路由。在另一个实施例中，如果分区逻辑拓扑不产生两个或更多个路由或者作为独立实施例，则源节点可以向目的地节点发送RREQ消息而没有任何对应的逻辑拓扑。目的地节点接收RREQ消息，并且可以基于目的地节点处的接收到的RREQ消息和路径选择标准来确定从源节点到目的地节点的两条或更多路由（例如，由目的地或源节点）。

摘要： In one embodiment, a more capable device (MCD) in a computer network may determine one or more a critical destinations (CDs), and may transmit an unsolicited reactive routing route request (RREQ) message to each CD. The MCD may then receive a route reply (RREP) message from the CDs having a route from the MCD to the CD, and may store the route at the MCD. Subsequently, the MCD may transmit a RREP message of its own to one or more less capable devices (LCDs) to provide the route from each respective LCD to the CD via the MCD.
摘要翻译：在一个实施例中，计算机网络中更有能力的设备（MCD）可以确定一个或多个关键目的地（CD），并且可以向每个CD发送未经请求的无效路由选择路由请求（RREQ）消息。然后，MCD可以从具有从MCD到CD的路由的CD接收路由答复（RREP）消息，并且可以将路由存储在MCD处。随后，MCD可以将自己的RREP消息发送到一个或多个不太有能力的设备（LCD），以通过MCD提供从每个相应LCD到CD的路由。
