  Link Metrics for the Mobile Ad Hoc Network (MANET) Routing Protocol

Abstract

   OLSRv2 includes the ability to assign metrics to links and to use
   those metrics to allow routing by other than minimum hop count
   routes.  This document provides a historic record of the rationale
   for, and design considerations behind, how link metrics were included
   in OLSRv2.
