@RichQ precisely! There was an active participation by NIST folks in TIA-TR50 committee as NIST was also involved in Smart Grid Interoperability Standards. NIST in my opinion is atypical of other goverment bodies that meddle in regulations!
Absolutely. I don't think it is a good idea to run full-blown TCP/IP stack on IoT devices. There are at least 2 reasons. Firstly, the footprint may not fit well. By increasing memory size, the power consumption becomes a challenge. Secondly, the longer the packet, the higher the power consumption on transmit.
There might be a role for government in standards that affect public safety, but I don'tthink that governments need to (or should) be involved in most commercial applications of the IoT. The people working in the field have a much better handle on the needs and challenges than anyone in government. And I trust market forces to work out a standard eventually.
The trouble with having a single standard communications protocol is that it may be too complex for some applications and perhaps not capable enough for others. I have difficulty with the idea that my IoT thermometer reading outside temperature every few minutes will use the same protocol as the IoT devices monitoring the real-time performance of a jet engine. My expectation is that different application domains will choose their own sets of standards to use. I agree that security needs to be a key part of any reference architecture, though.
A standard communication protocol will definitely enable better competitive market and will ultimately help advancing the technology. However, a standard could introduce security issue. I'm sure all these organizations have put in a reference architecture with security in mind. Question is whether there can be a better collaboration between different standard bodies so that there are at least a standard for communication between clusters following different standards.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
