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.
