Bursty-link-aware adaptive link quality estimation method

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.
