    摘要： In an example embodiment, an apparatus comprising an interface configured to communicate with at least one wireless transceiver, and a controller coupled to the interface. The controller is configured to determine a predefined characteristic such as current load and/or interference for a wireless channel associated with the at least one wireless transceiver. The controller is operable to suppress sending a probe response in response to the at least one wireless transceiver receiving a probe request, wherein how often probe responses are suppressed is based on the predefined characteristic for the wireless channel.

    摘要： In one embodiment, a receiving node in a computer network may detect congestion, and also identifies a set (e.g., subset) of its neighbor nodes. In response to the congestion, the receiving node may assign a transmission timeslot to each neighbor node of the set based on the congestion, where each neighbor is allowed to transmit (synchronously) only during its respective timeslot. The assigned timeslots may then be transmitted to the set of neighbor nodes. In another embodiment, a transmitting node (e.g., a neighbor node of the receiving node) may receive a scheduling packet from the receiving node. Accordingly, the transmitting node may determine its assigned transmission timeslot during which the transmitting node is allowed to transmit. As such, the transmitting node may then transmit packets only during the assigned timeslot (e.g., for a given time). In this manner, congestion at the receiving node may be reduced.

    摘要翻译： 在一个实施例中，计算机网络中的接收节点可以检测拥塞，并且还识别其相邻节点的集合（例如子集）。 响应于拥塞，接收节点可以基于拥塞来向组中的每个相邻节点分配传输时隙，其中每个邻居仅在其相应时隙期间被允许传输（同步）。 然后可以将分配的时隙发送到相邻节点集合。 在另一个实施例中，发送节点（例如，接收节点的邻居节点）可以从接收节点接收调度分组。 因此，发送节点可以确定其发送节点被允许发送的其分配的传输时隙。 因此，发送节点可以仅在分配的时隙（例如，给定时间）期间发送分组。 以这种方式，可以减少接收节点处的拥塞。

    摘要： A method determines wireless radio locations in a network. The method includes identifying a group of location fixed radios in a network. Radios in the network with known location coordinates and/or known timing bias error values are grouped. RTT values are determined between each radio in the group and radios outside the group. Timing bias error values are determined for each radio outside the group. The timing bias error value for each radio outside the group of radios with known location coordinates and known timing bias error values is based on the determined RTT values. Location coordinates are estimated for each radio outside the group. A request is received for access to the network from a mobile radio device. The known location coordinates and estimated location coordinates of radios are used to determine a distance of the mobile radio device from one of the location fixed radios.

    摘要： A multicast message may be distributed by receiving, at a first node in a multicast network, a multicast message from a parent node of the first node. The multicast message is transmitted to child nodes of the first node in the multicast network. A population of the child nodes to which the multicast message was transmitted is accessed and acknowledgement messages which reveal child nodes that are among an acknowledging subset of less than all of the child nodes of the first node are received. Child nodes revealed by the received acknowledgement messages are compared with child nodes determined to be among the population of child nodes to which the multicast message is expected to be received. Based on results of the comparison, a compressed non-acknowledging subset is identified and transmitted to the parent node.

    摘要： In one embodiment, a node may request to join a parent node in a directed acyclic graph (DAG) in a computer network, and may also notify the parent node of a load associated with the request and whether the node has any other parent node options. The requesting node may then receive a response from the parent node that is either an acceptance or a denial. While the node may join the parent node in response to an acceptance, if a denial is received, the node may divide the load into first and second portions, and may re-request to join the parent node with the load of the first portion. In this manner, by partitioning the load, a load balancing mode of operation across multiple is parents in a DAG is provided.

    摘要： A method of rate shifting specially suited for the voice traffic, which differentiates poor channel conditions from a heavily loaded channel of a WLAN and adapts to the network traffic condition and channel condition promptly with low rate of false shifting. Determining when to rate shift is based on a combination of the received signal strength indication and the retry rate.
