           Ad Hoc On-demand Distance Vector (AODVv2) Routing
                       draft-ietf-manet-aodvv2-11

Abstract

   The revised Ad Hoc On-demand Distance Vector (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 rapid
   convergence in dynamic topologies.
