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).
