突发性链路感知的自适应链路质量估计方法
Bursty-link-aware adaptive link quality estimation method
摘要
Abstract
A bursty-link-aware and adaptive link quality estimation method,named EasiLQE.was proposed. The beacon packets are sent by nodes in a long-term period to probe the link quality. Meanwhile,nodes passively measure the mean value of RSSI of received packets. If the mean value of RSSI is lower than a certain threshold,the EasiLQE initiates the link quality estimation process in a short-term period. Finally,the EasiLQE uses error-based filter to estimate the link quality in future. The experimental results show that the EasiLQE can react quickly and accurately to persistent link quality changes in a short time,and also can smooth the occasional link quality fluctuations,which are not acute,to keep the link quality estimator stable,and decrease the estimation costs.关键词
