    摘要： A data flow from a source to a destination is routed in a multi-hop wireless network. Nodes are searched in the multi-hop wireless network for information of route metrics for the nodes, the information of the route metrics are received, a route that has a most optimal route metric for the data flow are determined based on the route metrics and a data flow metric of the data flow, and the data flow are received from the source via the route at the destination in the multi-hop wireless network.

    摘要： A network includes a plurality of nodes. A set of candidate nodes from the plurality of nodes is selected based on location information for the candidate nodes and a first node also in the network. A clustering algorithm is applied to the location information for the candidate nodes and the first node, and a subset of the set of candidate nodes closest to the first node is identified based on the results of applying the clustering algorithm.

    摘要： Distances are determined between an identified node and landmark nodes and milestone nodes in a network. The closest milestone or landmark node associated with a shortest of the measured distances is determined. A corresponding distributed hash table (DHT) overlay node is queried for distances between observed nearest nodes for the closest milestone or landmark node and the identified node. Distances between the identified node and the observed nearest nodes are calculated from distances received from the DHT overlay node and the measured distance to the closest milestone or landmark node. K-closest nodes from the identified node are selected from at least one of the closest milestone or landmark node and one or more of the observed nearest nodes based on the calculated distances.

    摘要： The present disclosure is directed to networks having reduced power consumption characteristics and associated methods. In one aspect, a method for reducing power consumption in a multi-hop network can include receiving data at a plurality of primary nodes in a multi-hop network and transmitting the data from the plurality of primary nodes to a plurality of secondary nodes. Individual primary nodes have nearest neighbors at a defined distance and the secondary nodes are spaced at a distance that is greater than the defined distance away from individual primary nodes. Data is transmitted from a given primary node to a secondary node by skipping at least one intervening node and reducing power consumption of the wireless network.

    摘要： Methods, devices, and machine readable media are provided for transmission in a network with active and sleeping clients. Some examples can include transmitting a first multicast stream of data in response to an active wireless client being associated with the wireless network device at a particular time. The method can include transmitting a second multicast stream of the data after the first multicast stream in response to a sleeping wireless client being associated with the wireless network device at the particular time and in response to a delivery traffic indication message count expiring. The first and/or second multicast streams of the data can be retransmitted a number of times (e.g., at different data rates). An active/sleep status can be maintained for the wireless clients. A unicast stream can be transmitted when the number of clients does not exceed a threshold.

    摘要： A priority queue assignment technique for quality-of-service (“QoS”) network flows in a network is provided. A network path is determined for an incoming flow including a plurality of network switches associated, with a plurality of priority queue levels. A priority queue level is determined for the incoming flow for at least one of the plurality of network switches in the network path based on priority queue levels of existing flows. The priority queue level of the incoming flow is adjusted, to dynamically balance flows over the plurality of priority queue levels for at least one of the plurality of network switches in the network path based on quality-of-service (“QoS”) requirements associated with the incoming flow.
