     Intermediate RREP for dynamic MANET On-demand (AODVv2) Routing
                         draft-perkins-irrep-01

Abstract

   The Dynamic MANET On-demand (AODVv2) routing protocol is intended for
   use by mobile routers in wireless, multihop networks.  AODVv2
   determines unicast routes among AODVv2 routers within the network in
   an on-demand fashion, offering on-demand convergence in dynamic
   topologies.  This document specifies an extension to AODVv2 (and
   possibly other reactive routing protocols) enabling intermediate
   nodes to shorten route discovery times.

1.  Overview

   The Dynamic MANET On-demand (AODVv2) routing protocol enables on-
   demand, multihop unicast routing among participating AODVv2 routers.
   The basic operations of the AODVv2 protocol are route discovery and
   route maintenance.  Route discovery is performed by an AODVv2 router
   when one of its clients transmits a packet towards a destination for
   which the router does not have a route.  Route maintenance is
   performed to help ensure that the route being used to forward packets
   from the source to the destination remains operational.

   During route discovery, the originator's AODVv2 router initiates
   flooding of a Route Request (RREQ) throughout the network to find a
   route to a particular destination, via the AODVv2 router responsible
   for this destination.  During this hop-by-hop flooding process, each
   intermediate AODVv2 router records a route to the originator.  If the
   intermediate router has a route to the destination requested in the
   RREQ, it may by following the specification in this document supply
   that routing information to the originator of the RREQ.  Such an RREP
   message is termed an "Intermediate RREP" (iRREP).  The Intermediate
   router also forwards another RREP message to the requested
   destination, supplying the destination and other intermediate routers
   with a route towards the originator of the RREQ.  When the
   originator's AODVv2 router receives the iRREP, and the destination
   receives iRREP for the originator, routes have then been established
