The clustering routing method for heterogeneous cognitive wireless sensor networks relates to the technical field of wireless sensor networks, and solves the problems of high energy consumption, short network life cycle, shortage of spectrum resources and hardware constraints in wireless sensor networks, including random deployment of cognitive nodes and ordinary nodes; judge whether the remaining energy of cognitive nodes is greater than E max , if it is greater than E min , if it is less than , exit, otherwise, randomly select a number between [0, 1], compare the number with the probability of being elected as a cluster head, if it is less than, exit, otherwise, it becomes a cluster head; non-cluster head nodes according to the free transmission mode and the energy amplification factor in the multipath transmission mode, its distance to the base station and its distance to the cluster head to select the cluster head to join the cluster, and the probability of the cluster head being selected is determined according to the number of vacant channels and the edge degree. The invention reduces the energy consumption of the network, prolongs the life cycle of the network, relieves the spectrum shortage and avoids the problem of high hardware demand.

A bidirectional light transmission subassembly comprises a substrate, a multi-core connecting piece, a first light output module, a second light output module, a light reception module, an output circuit board and a reception circuit board. The substrate includes a first side, a second side and a bearing surface. The multi-core connecting piece is placed at the first side. The first light output module is placed on the substrate and coupled to the multi-core connecting piece via an output fiber. The second light output module is placed at the bearing surface and coupled to the multi-core connecting piece via another output fiber. The distance from the optical axis of the first output module to the bearing surface is the same with that from the optical axis of the second output module to the bearing surface, and the optical axis of the first output module is close to that of the second output module. The light reception module is placed on the substrate and coupled to the multi-core connecting piece via a reception fiber. The output circuit board is placed at the second side and electrically connected with the first and second light output modules. The reception circuit board is placed at the second side and electrically connected with the light reception module.

The embodiment of the present invention provides a baseband unit, a base station, and a data forwarding processing method. The data to be forwarded is received by the front-end switching module, and then the forwarding control module performs forwarding path matching on the data received by the front-end switching module according to the preset forwarding flow table. , when it is determined that there is data to be forwarded to the transmission interface module according to the matching result, the data is forwarded to the data exchange sub-module in the transmission interface module; since the forwarding path matching process is advanced, when a certain data is not sent to the transmission interface module, the data does not need to pass through the data exchange sub-module, but can be sent directly by the forwarding control module through the front-end switching module, which avoids the data return process between the data exchange sub-module and the forwarding control module, thus reducing the time Delay increases the amount of data transmission per unit time and further increases the bandwidth, so users can get a better experience.

The invention discloses a power cable with a high signal to noise ratio. The power cable comprises three main conducting lines and at least one auxiliary conducting line. The axes in the axial direction of the three main conducting lines are arranged in a triangular shape. At least a part of the auxiliary conducting line is located in a gap space among the main conducting lines. The peripheries of the main conducting lines and the auxiliary conducting lines are filled with insulation materials and covered with the insulation materials into a whole. The peripheries of the insulation materials are provided with a corrugated aluminum sheath. The periphery of each corrugated aluminum sheath is provided with an armor layer formed by two layers of armor electric wires in a winding mode and the armor electric wires of the two armor layers are wound in different directions. The periphery of each armor layer is covered with a protective sleeve. Each main conducting line comprises a core line conductor and a shielding layer covering the core line conductor and each auxiliary conducting line comprises a plurality of densely-arranged core line conductors and a shielding layer covering the core line conductors. The diameter of each core line conductor of each auxiliary conducting line is smaller than that of the core line conductor of each main conducting line and the diameter of each auxiliary conducting line is smaller than that of each main conducting line. One main conducting line serves as a signal transmission line. The power cable with the high signal noise ratio is simple in structure and high in anti-jamming capacity.
