[ipwave] Adaptive RESTful Real-time Live Streaming for Things (A-REaLiST)'

[Abhijan Bhattacharyya <[e-mail]>]

Dear list,
We submitted a draft in CoRE with a technical proposal for efficient transfer of time-series stream and presented in IETF Bangkok. The immediate use case that we considered was to transfer First Person View (FPV) video from a remote drone to a control unit over IP based infrastructure. We built it on CoAP leveraging some of CoAP's unique features. The ambition is to create a protocol stack that would be equally good in sending small sporadic bytes (sensor data) as well as streaming infinite time-series (like live video) while ensuring good QoE despite being low on resource consumption. 

The draft is available here: https://tools.ietf.org/html/draft-bhattacharyya-core-a-realist-00 

Probably, the use case that we had in mind and the technology we proposed, both can be extended to the purview of this WG.

Requesting your views on this draft please. If relevant then we can present this draft in Prague.

Here is the abstract for your ready reference:

   This draft presents extensions to Constrained Application Protocol
   (CoAP) to enable RESTful Real-time Live Streaming for improving the
   Quality of Experience (QoE) for delay-sensitive Internet of Things
   (IoT) applications. The overall architecture is termed ''Adaptive
   RESTful Real-time Live Streaming for Things (A-REaLiST)''. It is
   particularly designed for applications which rely on real-time
   augmented vision through live First Person View (FPV) feed from
   constrained remote agents like Unmanned Aerial Vehicle (UAV), etc.
   These extensions provide the necessary hooks to help solution
   designers ensure low-latency transfer of streams and, for contents
   like video, a quick recovery from freeze and corruption without
   incurring undue lag. A-REaLiST is an attempt to provide an
   integrated approach to maintain the balance amongst QoE, resource-
   efficiency and loss resilience. It provides the necessary hooks to
   optimize system performance by leveraging contextual intelligence
   inferred from instantaneous information segments in flight. These
   extensions equip CoAP with a standard for efficient RESTful
   streaming for Internet of Things (IoT) contrary to HTTP-streaming in
   conventional Internet.



Thank you. Looking forward.

P.S. The work has been accepted and presented in Wi-UAV workshop in Globecom, Dec,  2018. The public link to the paper is yet to be available.
