      Ad Hoc On-demand Distance Vector Version 2 (AODVv2) Routing
                     draft-perkins-manet-aodvv2-00

Abstract

   The Ad Hoc On-demand Distance Vector Version 2 (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.
