Abstract :
For the shortage of the traditional sink nodes of WSNs in refining and compressing the uplink data, a new method is proposed to design and implement a super sink node with the hardware fusion technology. This method adopts FPGA as the platform of the node and applies BP neural networks with systolic array structure, map arithmetic, stream line and nonlinear activation functions to achieve the hardware fusion of uplink data. The experiment shows that the proposed method has decreased the total amount of data, reduced the transmission bandwidth and improved the performance of real-time transmission.
