What is the difference of Internet from World Wide Web?
Internet simply means to connect networks between themselves. It provides us many services, Web being one of them. Web uses URLs to identify Web resources and HTTP
to access them.

System Design for the Internet of Things

Compare IoT to Wireless Sensor Networks (WSN)
IoT includes interaction, WSNs just collect data

IoT is not necessarily wireless

e IoT to “Ubiquitous Computing” (UbiComp)
•IoT requires a network, ubiquitous computing not necessarily
•Ubiquitous computing is not necessarily embedded in objects

System Design for the Internet of Things

e IoT to “Cloud Computin
•The cloud is a loose collection of connected computers.
•Cloud computing is about shifting the computation to the cloud in order to do more
complex computations
•The cloud is not bound to specific objects, it has no location
•The resources of the cloud are almost unlimited, IoT devices are constrained

System Design for the Internet of Things

IoT to “Big Data
•Big Data focuses on data and information and how knowledge can be extracted
from it.
•IoT is about the objects that generate and receive that data.

IoT to “Ambient Intelligence” (AmI)
AmI refers to electronic environments that are sensitive and responsive to the
presence of people.
•Ambient Intelligence formulates a task or application of IoT
•IoT provides an architecture without specific tas

System Design for the Internet of Things

IoT to Machine-To-Machine (M2M) network
•M2M is mostly bound to a single specialized application
•M2M does not include cloud services
•IoT includes user interaction with people (H2M, M2H
