摘要 能量消耗是无线传感器网络的关键问题之一,将DS-CDMA技术与WSN相结合提出了在马尔可夫信源模型的基础上采用能量优化的信源编码,从而降低能耗。仿真结果表明,能量优化编码可以有效地提高系统的信噪比、降低误码率、优化能量的使用效率。 Reducing power consumption is one of the key problems in wireless sensor network systems.This paper introduces a source coding method for power saving in DS-CDMA for WSN based on the model of Markov.Finally,simulation is conducted to verify the method which demonstrates the low BER and high SNR,and optimizes the power consumption.
