Summary

In this final chapter, we covered practical issues and challenges that are typically encountered while implementing IoT solutions/use cases. It listed key lessons learned from my past IoT projects. Specific references were made to two frameworks (Bain’s and Porter’s) as these can help to gauge as well as articulate the benefits/value of the envisaged IoT solution(s). It also listed the key NFRs and emphasized the importance of focusing on them during the complete project life cycle and covered two examples (power and cost optimization) in detail. Finally, it provided a representative list of IoT connectivity protocols, along with the scenarios in which they are most appropriate.

The IoT ecosystem, in general, is very dynamic, new techniques/technologies are continuously being discovered, and existing ones getting refined/evolved. Going forward, the trend is expected to continue with advancements expected at all layers of the IoT reference architecture. Some...
