We beleive WebRTC is a perfect communication solution for IoT. WebRTC features:

• real-time communication capabilities
• open-source and supported by Apple, Google, Microsoft and Mozilla, amongst others
• supports video, voice, and generic data to be sent between peers
• available on all modern browsers as well as on native clients for all major platforms
• technologies behind WebRTC are implemented as an open web standard and available as regular JavaScript APIs in all major browsers
• for native clients, like Android and iOS applications, a library is available that provides the same functionality
• WebRTC works behing the NAT

  FPGA provides a programmable hardware capabilities for IoT

• acceleration of computational algorithms
• implementation of custom hardware cores
• flexibility in accessing GPIO
