Abstract

In order to improve the communication performance of water immersion sensor,aiming at the problems of communication delay and high energy consumption,which affect the data capacity,a method based on wMBUS water immersion sensor spread spectrum coding communication technology is proposed.The wMBUS communication mode is applied to the communication of water immersion sensor.The Rayleigh fading caused by underwater acoustic channel is analyzed.The photonic crystal carrier algorithm is used to calculate the signal carrier beam to improve the data capacity of the communication beam of water immersion sensor.Through the frequency domain capacity expansion algorithm,the communication beam after binding and capacity expansion is improved to realize the spread spectrum coding communication of water immersion sensor.The experiment results show that the proposed method has low collision node probability,low communication delay,low communication energy consumption and high delivery rate.
