Re: [Coma] Reprogramming Protocols

["Pascal Thubert (pthubert)" <[e-mail]>]

Hum... I do not necessarily agree.

RPL, which is probably a protocol of choice for such environment, defines Objective functions that handle metric interpretation and some logic to tie multiple metrics and policies together.
I'd think that as long as we stay at the abstract (interface) level we can push some hints to an existing OF to twist its behavior, and tell RPL to support a new instance based on a new OF that needs to be installed.

There is probably a way to define:
- an abstract interface between RPL and the OF so that we can dynamically plug an OF in.
- abstract behavior specifications on which metric are supported and how they are handled (eg additive, weighted, etc) by an existing OF so we can tune the graph generation.
- abstract policies specifications so we can control peering, size, power, you name it.

What do you think?

Cheers,

Pascal

Hi Jonathan,

this could be seen under the SW/firmware distribution, however reprogramming protocol code is a device specific logic and not a management task.

Cheers,

Subject: [Coma] Reprogramming Protocols

Hi,

One thing that hasn't yet been mentioned (unless I missed it) is the issue or reprogramming protocols for adding new applications or modifying/patching existing applications/firmware. I imagine this is of particular interest in Sensor Nets but may also be beneficial in other scenarios. Will this also be considered within coma?

Thanks,

Jonathan
