    摘要: The present invention is a method for tactical spectrum harvesting via a cognitive communication device. The method may include monitoring a wireless communication frequency spectrum. The method may further include detecting active net communication transmissions. The active net communication transmissions may be transmitted via the monitored communication frequency spectrum by a plurality of active transmitting nets. The method may further include determining an identity of/identifying at least one active transmitting net included in the plurality of active transmitting nets. The method may further include synchronizing an internal time reference of the cognitive communication device with a time reference(s) of the identified active transmitting net(s). The method may further include determining an estimated future spectral occupancy for the identified active transmitting net(s) based on time data for the active net communication transmissions, cryptographic key data for the active transmitting nets, and algorithm data for the active transmitting nets.

    摘要: A method includes determining that a first receiver of a node of a mobile ad-hoc network (MANET) is in an electromagnetic contested environment for a first frequency. The method also includes scanning a frequency coverage range of a second receiver of the node for unused frequencies. The method additionally includes selecting a frequency from the unused frequencies, the selected frequency to be used for communication of messages from another node of the MANET to the node via the second receiver. The method further includes transmitting, to the other node, a message including information of the selected frequency via the transmitter.

    摘要: A method of operation for managing network security features is disclosed. A communication device such as a mobile telephone or a modem can establish a position as a communications intermediary supporting communications between a first communication device such as a personal computer and a third communication device such as a server. The intermediary can detect a security feature between these “end devices”, and disable security features on intermediate segments of the end-to-end communication link. The end-to-end communication may utilize a virtual private network as a security feature and other security features on the intermediate segments can be disabled when they provide negligible additional security for the communications.

    摘要: Methods (400, 500) and corresponding systems (100) for handing off between a broadcast network and a cellular network include receiving, in a cooperation platform, incoming data from a content provider. Broadcast data corresponding to the incoming data is then sent to a broadcast network output for broadcasting to one or more subscribers including, a subscriber station. Handoff information from the cellular network is received in the cooperation platform, and, in response to the handoff information, cellular data corresponding to the incoming data is sent to a cellular network output for transmission to the subscriber station. The handoff information can correspond to a user request for handoff sent from the subscriber station via the cellular network, or can be a request for handoff sent from the cellular network based upon a loading level within one or more of the broadcast network and the cellular network.
