Internet of Things Architecture, Protocols and Smart City Apps
Module 1 – Introduction to IoT (ECT 458)
IoT: Global network of physical/virtual “things” with unique identities, exchanging data via interoperable protocols. Enables data sensing, collection, sharing, and intelligent actions with context awareness.
Characteristics
- Dynamic / Self-adapting — responds to context changes (e.g., day/night cameras).
- Self-configuring — automatic updates and network configuration.
- Interoperable protocols — supports multiple standards.
- Unique identity — IP, URI, or

“The Great Wave off Kanagawa” is a famous Japanese ukiyo-e print created by Hokusai around 1831.

Consumer Behavior: Utility & Indifference Curves
This unit explores how consumers make choices to maximize their satisfaction.
Key Concepts
Utility: The want-satisfying power of a commodity.
Cardinal Utility: Assumes utility can be measured numerically (e.g., in “utils”). This is the basis for the Marginal Utility Analysis.
