  • Publication number: 20120250694
    Abstract: A communication system comprises a plurality of nodes and a switch having a plurality of ports, each port coupled to one of the plurality of nodes. At least one of the plurality of nodes is configured to transmit a first unregulated flow of frames associated with a first virtual link to a first port of the plurality of ports of the switch. The switch is configured to regulate the first unregulated flow of frames by buffering frames of the first unregulated flow in a first input queue associated with the first virtual link, applying traffic shaping parameters associated with the first virtual link to the frames in the first input queue associated with the first virtual link, and outputting the first regulated flow of frames to one or more output queues associated with one or more output ports based on the first virtual link.

  • Patent number: 8193969
    Abstract: A system and method for maintaining spatio-temporal data for a given area (e.g., an airspace) containing a given node (e.g., an aircraft) and one or more other nodes (e.g., aircraft). The given aircraft may break the given airspace into a first plurality of smaller airspaces, and may also break the given airspace into a second plurality of smaller airspaces. The given aircraft may then detect local spatio-temporal data for each smaller airspace located within its detectable range. The aircraft may also receive remote spatio-temporal data for the smaller airspaces from the one or more other aircraft. Thereafter, the aircraft may update stored spatio-temporal data based on the aircraft's navigation data, the local spatio-temporal data, the remote spatio-temporal data, and/or a reliability of the data. Further, the aircraft may transmit the stored spatio-temporal data for receipt by the one or more other aircraft.

  • Patent number: 8107387
    Abstract: A method for operating a wireless network having a predicable and stable network performance. The method includes controlling output distribution of nodes in the network to adapt to traffic changes in the network, distributing power control to adapt to environmental changes in the network, and providing traffic sensitive routing to adapt to topology changes in the network. The method also includes converging to set points based on the controlling of output distribution, the distributing of power control, and the providing of traffic sensitive routing.

  • Publication number: 20090303888
    Abstract: A method for optimizing a wireless network comprises obtaining local measurement and feedback data from a single node in the network; estimating a state of the node by using the local measurement and feedback data in an analysis framework model of the wireless network; applying the estimated state of the node to a local control law to determine one or more local protocol parameter updates for the node; and transmitting the one or more local protocol parameter updates to the node in the network.

  • Publication number: 20090259862
    Abstract: A clock module is coupled in parallel to a number of data processing modules that are coupled in series. The data processing modules can be individually clock-gated. Each of the data processing modules can determine whether or not it can be placed into an idle state. To reduce power consumption, any subset of the data processing modules that are eligible to be placed in an idle state can be clock-gated. The remaining data processing modules can continue to receive clock signals from the clock module and thus can continue to process data.

  • Patent number: 7486221
    Abstract: A method and system are disclosed where transmitted radar pulses are utilized for both a radar sensing function and for data communications. The data communications are performed in a manner that is simultaneous and transparent to the radar sensing function, in terms of non interference or interruption. The method and system are applicable to data communications between multiple pulsed radar devices as well as radar devices that are capable of receiving pulsed transmissions and transmitting continuous wave transmissions.

  • Patent number: 7460549
    Abstract: An initiator node in a local cluster included in a wireless network receives an admission request to execute an application comprising a set of tasks. If the initiator node is unable to map the set of tasks to nodes included in the local cluster, the local cluster head node forwards the admission request to the cluster head node of successive clusters in the wireless network in order to have at least one node in each of the successive clusters send resource availability information to the initiator node. The initiator node attempts to map the set of tasks to a subset of the nodes from which resource availability information has been received. This is repeated until the initiator node is able to map the set of tasks to a subset of the nodes in the wireless network or until there are no additional clusters to forward the admission request to.
