研究无线传感器网络系统中信道链路质量的指示问题。指出了RSSI作为指示量的缺点,通过合理的设计及大量的检测数据,分析验证了平均Corr值对信道链路质量的指示比RSSI值更加有效,同时具有获取时间短的特点,对无线传感器网络功率控制的实现具有参考价值。
Research on the indication of channel link quality in wireless sensor network system. Pointed out the shortcoming of RSSI as the indicator, through the reasonable design and a large number of test data, it is verified that the average Corr value is more effective than the RSSI value in the indication of the channel link quality, and has the characteristics of short acquisition time. The wireless sensor network The realization of power control has reference value.
