Lecture 10: Introduction to Internet of Things (IoT)

Internet of Things (IoT)

• IoT is the network of physical objects embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data.
• IoT is everywhere and has various applications.

Smart Home

• A smart home is a house with appliances that are connected to the internet and can be controlled via smartphone.
• Features of smart home technology include:
  • Control: lighting, TV, thermostat, appliances, door locks, and more
  • Convenience: automatically reduces TV volume when receiving a land-line call
  • Security: door locks and security systems
  • Health: monitoring and responding to health needs

Big Data

• Big data is high-volume, high-velocity, and high-variety information assets that require new forms of processing to enable enhanced decision making and insight discovery.
• Characteristics of big data:
  • Volume: exceeds limits of traditional relational databases and grows constantly
  • Velocity: arrives rapidly and often in real-time
  • Variety: does not have a standard structure (e.g., text, images, audio)

Data Structures

• Four main types of data structures:
  • Structured data
  • Quasi-structured data
  • Semi-structured data
  • Unstructured data

Generation of Big Data

• Sensors gathering information (e.g., climate, traffic)
• Social media: posts, pictures, and videos
• Digital satellite images
• Purchase transaction records
• Mobile phone GPS signals
• High-volume administrative and transactional records

Data Analytics Lifecycle

• Discovery: identify problem or opportunity
• Planning: define problem, determine objectives, and identify data needs
• Data prep: collect, clean, and transform data
• Model building: develop and refine models
• Operationalize: deploy and monitor models
• Communicate results: share insights and recommendations

Industry Examples for Big Data Analytics

• Healthcare: reducing cost of care, preventing pandemics
• Life Sciences: genomic mapping, unstructured data analysis
• IT Infrastructure: phone/TV, online services, retail, financial services
