Abstract: A channel allocation method based on Shapley value in wireless networks is provided. The method comprises: disclosing by a PU (primary user) some idle channels denoted by serial numbers, a utilization rate threshold, a lowest selling price, and an increment between two bidding prices; SUs (secondary users) reporting the corresponding numbers of required channels to the PU; calculating a plurality of legal teams satisfying the utilization rate threshold; classifying the plurality of SUs; calculating the Shapley value of each SU in each legal team; calculating an estimated price of each multi-user in each legal team; determining the retained legal teams; performing an ascending auction process by the retained legal teams; and allocating the channels to the SUs in the winning team.

Abstract: A method for detecting surroundings of a software radio is provided, wherein the software radio comprises a first directional antenna and a second directional antenna, and the method comprises: sending a directional signal towards a preset direction by the first directional antenna; receiving a return signal from the preset direction by the second directional antenna, and obtaining a round trip time according to the directional signal and the return signal; obtaining a distance between the software radio and an object in the preset direction according to the round trip time; adjusting the preset direction and repeating above steps, until distances between the software radio and objects in respective directions are obtained; obtaining the surroundings of the software radio according to the distances between the software radio and objects in respective distances.

Abstract: A electricity transmission sending device includes: a transmission circuit and a coil, where the transmission circuit includes a signal sending unit and a controlling unit, and the coil includes at least two mutually perpendicular subcoils. The signal sending unit is configured to receive a required power signal and an actually received power signal that are sent by the electricity transmission receiving device; and the controlling unit is configured to adjust a magnetic field direction in which wireless electricity transmission to the electricity transmission receiving device is performed and control the coil to transmit electric energy to the electricity transmission receiving device in an optimal magnetic field direction, where the optimal magnetic field direction refers to a corresponding magnetic field direction when a power value of electric energy actually received by the electricity transmission receiving device is maximum in a case of specific output power of the coil.

Abstract: The present disclosure relates to a method including: receiving resource requests from clients and converting the resource requests into search requests in sequence; searching a resource list of sensor nodes of cloud according to search conditions of the search request and obtaining a resource ID of the sensor node that meets the search conditions; searching a data list of the sensor node and reading a working frequency of the sensor node in the resource list; comparing the working frequency with a desired frequency in the search conditions to determine if buffered data in the data list can meet requirements; feeding back the buffered data to the clients if the buffered data meets the requirements; and controlling the sensor nodes to collect data according to the search conditions and priorities of the sensor nodes and sending the collected data to the clients if the buffered data cannot meet the requirements.
