Hardware

The heart of IoT is billions of interconnected devices with attached sensors and Actualators that sense and control the physical world.

In addition to network connectivity to transmit the data they collect these devices require some basic processing and storage capabilities provided by a micro controller Or by an integrated circuit such as a System on a Chip Or a field programmable gate array.

Embedded programming

IoT devices are embedded devices and may be prototyped using commoditized micro controller platforms such as Arduino with custom printed circuit boards developed at a later stage.

The embedded programs are often developed using c++ or c. However python and javacript are becoming more popular for prototyping IoT devices.

Security

Security is one of the most critical concerns in IoT closely related to data ethics privacy and liability with millions of new devices connected every day the number of potential points of attack grows daily.

With so much at stake security engineering skills including threat assessment ethical hacking encryption to ensure data integrity securing the network and more move to the foreground of the IoT development projects.

Networking and cloud integration

Network design and management are essential within IoT due to the sheer volume of connected devices and due to the impact that network design decisions can have at scale.

Connectivity enables devices to communicate with other as well as with applications and services that are running in the cloud.

Data analystics and prediction

The number of IoT devices transmitting data increases on the daily basis which turns big data into huge data developers will need securely and reliably ingest, store and query the vast quantities of heterogeneous data originating from these device.

Besides as many IoT devices generate latency or time sensitive data it is also necessary to filter or discard irrelevant data.

Machine Learning and AI

To deliver value and make sense of the huge volumes of data that is generated by IoT devices machine learning and Al skills are the ultimate must have skill for IoT developers.

To be truly intelligent big data analytics needs to apply cognitive computing techniques drawn from data mining, modeling, statistics, machine learning and AI.
