Abstract : In Mobile Ad hoc networks MANETs, advanced routing metrics use Link Quality Estimators LQE for making routing decisions.
To be efficient and in a strong interaction with the physical layer transmission conditions, the accuracy and the reactivity of LQE used by metrics are crucial for maintaining connectivity.
Current LQE estimates the link quality into a single value.
This method limits the accuracy of the estimators, especially in highly volatile environments such as VANETs in urban environments.
In this paper we propose multi-estimators LQE approach that provides both a better link quality and a link behavior assessment.
These novel estimators deal with LQE requirements, reactivity , stability and accuracy to become a reliable LQE.
We evaluate they reactivity and accuracy with realistic physical layer and mobility patterns and also found their forecasting properties.
