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： 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： An IPv4 host is able to maintain connectivity within an access network while moving among access points of the access network, based on receiving a unique assigned IPv4 address from a clusterhead of the access network. Any DHCP request by the IPv4 host is sent via the connecting access point to the clusterhead. The clusterhead, providing connectivity for hosts in the access network to a wide area network based on respective entries, assigns the IPv4 address to the IPv4 host, based on storing an entry including the IPv4 address and an IP-based identifier of the connecting access point, and sends a DHCP response to the IPv4 host via the connecting access point. A second DHCP request from the IPv4 host to a second access point causes the clusterhead to update the entry with the second access point identifier, enabling the IPv4 host to continue use of the assigned IPv4 address.
摘要翻译： 基于从接入网络的集群头接收唯一分配的IPv4地址，IPv4主机能够在接入网络的接入点之间移动时保持接入网络内的连接。 IPv4主机的任何DHCP请求都将通过连接接入点发送到集群头。 基于相应条目向群集网络中的主机提供连接的集群头基于存储包括IPv4地址的条目和连接接入点的基于IP的标识符，将IPv4地址分配给IPv4主机 ，并通过连接接入点向DHCP主机发送DHCP响应。 从IPv4主机到第二接入点的第二个DHCP请求导致集群头部用第二接入点标识符更新该条目，使IPv4主机能够继续使用分配的IPv4地址。
