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.
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.
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.
@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!
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.
