Design Method of High Speed Data Exchange Node for Internet of Things

Aiming at the problem of high power consumption and low overall performance, a new design method of high speed data exchange node for Internet of Things (IoT) is proposed. The topology of IoT at the node is designed, and the modulation module, codeword addition module, and demodulation module are designed. Make each node IP and high speed data exchange module through the input port and the output port and the switching node, set a buffer queue at each input port, read data through the modulation module, transmit to code adder module for the addition operation. Results will be sent to each demodulation module after processing, and the data is transmitted to the destination IP module. The software design of high speed data exchange node is realized by Code Division Multiple Access (CDMA) technology. The experimental results show that the proposed method has high bandwidth utilization, fast transmission speed, and strong response ability.
