Accuracy of link status detection in wireless multi-hop networks
Bratislav Milić, Miroslaw Malek · 2010
We analyze accuracy of hysteresis link status detectors in static and mobile wireless multi-hop networks (WMNs), with focus on errors in link status detection caused by the unreliable communication channel. The hysteresis link status detectors are of particular importance in WMNs due to their use in various protocols, such as AODV and OLSR. Stochastic models are derived that describe hysteresis link status detector behavior as a function of detector parameters and network characteristics. Models are applied to a real network and their analysis shows that the probability of errors in link status detection in WMNs is considerable. In order to reduce these errors, we optimize detector parameters so that the link detection error probability is minimized.
