【摘要】 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.更多还原

【Abstract】 A bit error rate guided packet length optimization algorithm(BGPP) is proposed to solve the energy waste problem caused by lower useful data rate.According to the receiver’s feedback bit error rate of the wireless link,BGPP uses a lossless data aggregation method,which adjusts the packet length dynamically,to improve the useful data rate of packets.Experiments indicate that BGPP adapts the packet length to the wireless link quality dynamics and saves more energy when bit error rate of the wireless link is lower.更多还原
