Hello Samita,
I will contribute, but do you have a specific deadline for us to send
you comments?

Hello all:
In 6lowpan workgroup, we developed draft-ietf-6lowpan-nd which
provides optimization of IPv6 ND for IEEE802.15.4 devices by avoiding
all-node and solicited-node multicast messages for the most part and
providing a method for device registration with a IPv6 Border router
in a route-over topology and as well as single-hop topology.
In the last IOT workshop at IETF, it has been brought up that the
6lowpan-nd like document may be useful in many other cases where
devices are not IEEE 802.15.4 devices but the nodes are basically
energy-aware and like to save energy as much as possible. 'Hello' or
periodic advertisement/solicitation messages generally work well for
line-powered devices, yet reducing the periodic messages may be useful
for less power consumption for each connected device and therefore
reducing overall energy consumption of the network. Needless to say
that the reduced number of messages and avoidance of periodic all-node
or solicited-node multicast messages are critical for some low-powered
device operations. With EUI-64 IID, a DAD is not necessary if the
deployment may choose to do so.
Here is an attempt to put together the first draft for generic
optimization for energy-aware IPv6 networks:
http://tools.ietf.org/html/draft-chakrabarti-nordmark-energy-aware-nd-00
Comments are welcome. Would like the help from the community to shape
this document up for generic energy optimization for IPv6 ND in
applicable cases. This document also discusses a way of prefix
dissemination for address auto-configuration which may be useful in
future home network in a single prefix scenario. With the
proliferation of internet-of-things, it might be helpful to do address
auto-configuration in some isolated situations.
More work is needed in this document - it is the initial effort to
begin with.
Regards,
-Samita
