AODV based RPL Extensions for Supporting Asymmetric P2P Links in
Low-Power and Lossy Networks
draft-ietf-roll-aodv-rpl-09
Abstract
Route discovery for symmetric and asymmetric Point-to-Point (P2P)
traffic flows is a desirable feature in Low power and Lossy Networks
(LLNs). For that purpose, this document specifies a reactive P2P
route discovery mechanism for both hop-by-hop routing and source
routing: Ad Hoc On-demand Distance Vector Routing (AODV) based RPL
protocol (AODV-RPL). Paired Instances are used to construct
directional paths, in case some of the links between source and
target node are asymmetric.
