A Mechanism to Measure the Routing Metrics along a Point-to-point Route
                    in a Low Power and Lossy Network
                   draft-ietf-roll-p2p-measurement-09

Abstract

   This document specifies a mechanism that enables an RPL router to
   measure the aggregated values of given routing metrics along an
   existing route towards another RPL router, thereby allowing the
   router to decide if it wants to initiate the discovery of a better
   route.
