     Adaptive RESTful Real-time Live Streaming for Things (A-REaLiST)
                   draft-bhattacharyya-core-a-realist-00

   Abstract

   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.
