Performance Evaluation of Link Quality Estimators

The objective of this chapter is twofold: First, we present a methodology to evaluate the performance of LQEs regardless their type (e.g., PRR-based versus RNP or score-based, hardware-based vs. software-based). We follow this methodology to evaluate the performance of six representative and well-known LQEs in the literature. The results presented in this chapter should help network protocol designers fully understand the strengths and weaknesses of these LQEs, thus enabling them to make an informed choice.
