The article doesn't say much about the need for such an interface. Perhaps there are application which require higher frequency polling for sensor data but I thought those were adequately addressed by I2C as @markhahn also points out. Isn't this rather a design & implementation problem than a standards one?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
