Abstract

The invention provides a sense coexisting TD-SCDMA and sensor network convergence transmission system, belongs to the technical field of broadband wireless mobile communication networks and aims at the problem that data transmission of an existing wireless sensor network cannot adapt to the demands of complicated electromagnetic and geographical environments on different networking modes. The sense coexisting TD-SCDMA and sensor network convergence transmission system comprises a sensor node, an aggregation node and a central node. The sensor node is used for monitoring an electromagnetic frequency spectrum and transmitting monitored data to the aggregation node. The aggregation node is used for reporting a network topological graph and relaying and forwarding data. The central node is used for serving as a control node, issuing an instruction, summarizing frequency spectrum monitoring information and generating the network topological graph. The sensor node, the aggregation node and the central node respectively have Wi-Fi and TO-SCDMS transmission means, and the data can be transmitted in Wi-Fi and TO-SCDMS hybrid networks. The sense coexisting TD-SCDMA and sensor network convergence transmission system is used in a wireless sensor network.

Description

technical field [0001] The invention relates to a wireless sensor network transmission system, which belongs to the technical field of broadband wireless mobile communication network. Background technique [0002] The electromagnetic spectrum monitoring system of wireless sensor network is composed of three network devices: sensing node, sink node and central node. The sensing node is responsible for monitoring the electromagnetic spectrum, and gathers the monitored data at the sink node. The sink node can store, fuse or feature extract the data of the sensing nodes, and then transmit important data to the central node. The central node is responsible for summarizing all spectrum monitoring information and generating a network situation map. When necessary, the central node can also go to the sink node for data mining. The existing wireless sensor network electromagnetic spectrum monitoring system networking is not flexible enough, so it cannot meet the needs of different...
