Re: [RSN] Update

JP, I agree when you said in a previous email:

In addition, our routing scheme should know when the PAN 
coordinator/Gateway location has changed to lower and balance the network 
energy consumption.
Then new timezones can be assigned and data routed accordingly.

I am looking forward to seeing this new WG formed,
Best regards,
Anthony.

Re: [RSN] Update
Classification

We did some work to schedule a coordinate switching on and off of sensor 
nodes in order to reduce at maximum the energy consumption of the network. 

We came up with a routing protocol that allows us to route data throughout 
 the network according to the ON/OFF state of the nodes. 

We would like to provide input for an ID on routing schemes that have 
energy consumption as the first focus. 

Best regards, 
Anthony.

[RSN] Update 
Classification

Dear all,

Here is an update on where we stand: good progress !

1) We've been having quite a bit of off-line and on-line discussions 
and there is apparently a good level of interest in this work.
There are currently 5 IDs in the works:
* The generic routing requirements: draft-culler-rsn-routing-reqs
* Two application-specific routing requirements:
                - Home Networking
                - Industrial
* A problem statement
* An ID on routing metrics

Of course, if you're interested to work on these IDs or other items, 
feel free !

2) New name
Although we called this initiative RSN: Routing for Sensor Networks, 
it does apply more generally to constrained nodes (Low Power)
operating in Lossy Networks. Objects in general would typically be 
part of those networks. So from now on, let's rename this work
R2LN: "Routing issues for Low Power, Lossy Networks", and use that 
acronym in all IDs.

3) Next IETF
We asked for a presentation slot for the next IETF. Depending on the 
feedback, the next step would then to request a BOF in Vancouver.

Thanks.

JP and David.
