Approach for managing the use of communications channels based on performance
An approach for selecting sets of communications channels involves determining the performance of communications channels. A set of channels is selected based on the results of performance testing and specified criteria. The participant generates data that identifies the selected set of channels and provides that data to other participants of the communications network. The participants communicate over the set of channels, such as by using a frequency hopping protocol. When a specified time expires or monitoring of the performance of the channel set identifies poor performance of the set of channels, the participant selects another set of channels for use in communications based on additional performance testing. By selecting channels based on the initial performance testing and performance monitoring, the communications network adaptively avoids channels with poor performance. |

Dynamic resource allocation for sensor devices on a cellular network
A method and associated systems for on-demand cellular-network bandwidth allocation in response to continuously changing populations of sensor devices. A sensor device adds itself to or deletes itself from a cluster of sensors. A physical controller that manages the cluster detects this change, identifies a resulting change in the cluster's bandwidth requirements, and stores this information in a local database. When such a sensor-population change satisfies a triggering condition, the controller requests that a network-management component of the cellular network adjust the controller's bandwidth allocation. The network-management component aggregates this and similar requests from all connected controllers in a global database, and when controller bandwidth requirements satisfy a second triggering condition, the component, using a standard API, asks the network-management component to reprovision the component's virtual bandwidth allocation. The component then distributes the adjusted bandwidth among its sensor-cluster controllers, which in turn allocate their adjusted bandwidths among their sensor devices. |

In one embodiment, an integrated circuit may be designed using a library of clocked circuits that have programmable clock delays that may be inserted on the clock input to the clocked circuits.
