Poll: How Reliable is IoT?

IoT security is always at the top of the list of the Big Issues of IoT. There's also a lot of concern about wireless connectivity and power management. What about reliability? How reliable is IoT? Does IoT work when you need it work? If it isn't, what can improve IoT reliability?

 

Poll Question: How Reliable is IoT?

  • in reply to dougw

    The cloud is another word for social networking and data (ab)use.image

  • The sensors are okay but usually have a limited life.

    The solid state edge hardware is pretty reliable.

    My WiFi access point is a little flakey - needs a reboot every month or two.

    My router connection to the internet is okay but needs attention a couple of times per year.

    The Internet is very good.

    I don't really trust the cloud servers yet, not sure I will ever have absolute confidence in them - for several reasons.

    My own servers are reasonable - haven't actually had a failure yet.

  • I have voted other, because I find it hard to choose amongst the options available. This is not because the options do not cover all the possible answers, but because the answer would depend on what is intended by reliability, and what metrics are used to define it. If we identify reliability using, for instance, link uptime, we could probably say that most IoT systems are reliable, but things might change when we start using more fine-tuned metrics, like , for example, Packet Delivery Ratio (the ratio of the number of packets sent by the source node and the number of packets received by the destination node).

     

    As there are many possible parameters that can be used to define reliability, finding a "formula" to quantify it it is not trivial. Accidentally, this complexity makes the problem an ideal candidate for machine learning, and I have read a few papers where this approach has brought some promising results (for example Multi-Parametric Analysis of Reliability and Energy Consumption in IoT: A Deep Learning Approach).

  • I have a love-hate relationship with WiFi.

    With a wired connection it tends to just work reliably once you plug it in. The trouble is getting that ethernet cable to the device.

     

    WiFi is nice in that it connects up easily, but I've run into so many signal-strength issues, and WiFi AP name or password update pains, that I now try to connect via ethernet cable first whenever possible.

     

    And the Raspberry Pi... Pi WiFi hates me image

     

    For commercial IoT devices, I find the provider's website is often a huge performance bottleneck. And there's the worry that there are so many IoT startups competing for the space that the one I choose may not exist in a year or two.
