Studying on Power Saving to Wireless Network of Test and Control for Grain Situation Communication

本文采用偶数位标记编码算法对网络化无线粮情测控系统传感节点的传输数据进行压缩,减少传输数据所占的字节数,降低传感节点通信中的能量消耗及存储开销,提高了系统的传输可靠性。通过抽样数据验证,此方法可使传感节点通信传输能量降低率在30%-70%范围内,随采集数据数的不同而变化,节能效果明显。

This paper takes the even-bit-marking coding algorithm to compress transmitting data of the sensor nodes of wireless network of test and controlling for grain situation.Then it can reduce the number of bytes occupied by data transmission,cut down the energy consumption and storage overhead of sensor nodes communication,and improve the transmission reliability of the system.From the sampling data validation,we can show that this method can reduce the power of sensor nodes communication by 30%-70%,which varies with the number of collected data.The energy-saving effect is obvious.
