Study Notes

Benefits of IoT

Efficiency: IoT enables great data sharing and manipulating the data as needed, helping systems work more efficiently and make smarter decisions in real-time.
Transparency: IoT digitizes every process, providing greater transparency, and enables physical objects to remain connected, tracking inventory and parcels.
Automation and control: Machines communicate with each other, resulting in more time-efficient output, and automation ensures uniform completion of tasks and quality of services provided.
Accuracy: Automation reduces downtime and errors.
Information: Access to additional information enables improved decision making in diverse areas.
Time: IoT integration has the potential to save large amounts of time.
Security: Security sensors and location-based sensors enhance security.
Cost/money: IoT saves money by reducing errors, improving employee retention, and energy-efficient behavior.

IoT Challenges

Privacy: Collected data must be kept secure and anonymous when necessary.
Heterogeneity: IoT devices have different interfaces and communication protocols, requiring a common way to abstract the underlying heterogeneity.
Sensors: Sensors must be inexpensive, accurate, and energy efficient.
Networks: Transferring data and commands must be secure, reliable, and robust.
Big data: Connected devices generate large volumes of diverse data, requiring IoT to address time, resources, and processing capabilities.
Analysis: Data must be properly interpreted and analyzed with fidelity to its meaning, especially for automated actions.

What is IoT?

IoT is the broad connection of devices that can interact with each other and share data to a larger network.
Devices must have unique identifiers and use embedded technologies to sense and gather data about themselves and their environment, and transfer data to other devices or hosts.

Characteristics of IoT

Things or Devices: Connected objects that can sense, actuate, and interact with other objects, systems, or people.
Devices must have a processing unit, power source, sensor/actuator, network connection, and a tag/address for unique identification.

IoT and Big Data

Big data: Data sets that are too large or complex, coming from many sources in unstructured formats, and cannot be dealt with by traditional data-processing application software.
Big data characteristics: Volume (large amounts of data), Velocity (high rate of data generation), and Variety (many possible formats of data).
