RSSI-based Cross Layer Link Quality Management for Layer 3 wireless mesh networks

摘要

We propose a framework of link quality management for wireless mesh networks. In this method, Packet Error Rate for each rate of each link is estimated based on RSSI measured for received hello packets using noise parameter to select the optimum rate, such that the link metric becomes minimum. We present a method to estimate the noise parameter and show that the proposed method is promising using an actual testbed.
