Abstract: Cognitive radio adaptation is employed in WSNs to reduce effects of RF interference. Communication channel quality is assessed locally at each node. Using beacons to propagate channel quality and node related information among the nodes of the network, channel adaptation decision is made either centrally by identifying a channel that is optimum for a majority of nodes through a tree-structure dissemination (Majority Voting Scheme) or in a distributed manner by identifying a channel where maximum interference for any node is less than maximum interference on the other channels (Veto Voting Scheme). If two channels have the same level of maximal interference, the channel with a lesser number is chosen. Channel quality assessment may be optimized based on expected interference type and/or statistical methods.

Abstract: Methods of managing distributed analytics on device groups are described. In an embodiment, a management service within a distributed analytics system provides an interface to allow a user to define a group of devices based on a property of the devices. When the property of a device in the system satisfies the criterion specified by the user, the device is added to the group and the device may subsequently be removed from the group if the device no longer satisfies the criterion. Once a group has been defined, the management service enables users to specify management operations, such as creating, starting, stopping or deleting queries or management operations relating to other entities of end devices, which are to be implemented on all the devices in the group and the management service propagates the operation to all devices in the group, irrespective of their current connectivity status.
