Basic of IoT Networking ( Part - 1 )

Convergence of Domains

IoT Components

Functional Components of IoT

• Component for interaction and communication with other IoT devices
• Component for processing and analysis of operations
• Component for Internet interaction
• Component for handling Web services of applications
• Component to integrate application services
• User interface to access IoT

IoT Interdependencies

IoT Service Oriented Architecture

IoT Categories

Industrial IoT

• IoT device connects to an IP network and the global Internet.
• Communication between the nodes done using regular as well as industry specific technologies.

Consumer IoT

• IoT device communicates within the locally networked devices.
• Local communication is done mainly via Bluetooth, Zigbee or WiFi.
• Generally limited to local communication by a Gateway.

IoT Gateways

IoT and Associated Technologies

Technical Deviations from Regular Web

IoT Challenges

•  Security
• Scalability
• Energy efficiency
• Bandwidth management
• Modeling and Analysis
• Interfacing
• Interoperability
• Data storage
• Data Analytics
• Complexity management (e.g., SDN)

Considerations

• Communication between the IoT devices(s) and the outside world dictates the network architecture.
• Choice of communication technology dictates the IoT devices hardware requirements and costs.
• Due to the presence of numerous applications of IoT enabled devices, a single networking paradigm not sufficient to address all the needs of the consumer or the IoT device.

Complexity of Networks

• Growth of networks
• Interference among devices
• Network management
• Heterogeneity in networks
• Protocol standardization within networks

Wireless Networks

• Traffic and load management
• Variations in wireless networks - Wireless Body Area 
• Networks and other Personal Area Networks
• Interoperability
• Network management
• Overlay networks

Scalability

• Flexibility within Internet
• IoT integration
• Large deployment
• Real-time connectivity of billions of devices
