针对传感器数据传输过程中报文的有效数据比例较低所造成的能量浪费问题,提出一种基于无线信道误码率的报文优化算法(BGPP).该算法根据接收者反馈的无线信道的误码率动态调整发送报文的长度,采用无损的数据聚集方法来提高报文中的有效数据比例.实验结果表明,BGPP算法可以适应无线信道状态的动态变化,在无线信道误码率较低的情况下具有较好的节能效果.
Aiming at the problem of energy waste caused by low proportion of valid data in the data transmission process of sensor, a message optimization algorithm (BGPP) based on bit error rate of wireless channel is proposed. According to the error of wireless channel The bit rate dynamically adjusts the length of the sent message and uses a non-destructive data aggregation method to improve the proportion of valid data in the message.The experimental results show that the BGPP algorithm can adapt to the dynamic change of the wireless channel state, and when the bit error rate of the wireless channel is low The case has a good energy-saving effect.
