Ad Hoc On-demand Distance Vector Version 2 (AODVv2) Routing
draft-perkins-manet-aodvv2-03
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.
