What is the difference between the Internet of Things (IoT) and the Internet of Everything (IoE) as described in the chapter?

IoT focuses only on sensor networks, meaning machines communicating with other machines and the data that results. IoE is the next step beyond IoT, arising as connected things gain more capabilities and as more people and new information become connected, creating a vast network of networks with billions or trillions of connections.

The chapter distinguishes IoT and IoE by scope and evolution. IoT is limited to sensor networks where machines communicate with other machines and generate data from those interactions. IoE is described as the next phase beyond the mere connection of physical things: when those things add capabilities such as context-awareness, increased processing power, and energy independence, and when more people and new information are brought into the network, the IoT transforms into IoE. IoE therefore represents a network of networks with far larger numbers of connections, creating both unprecedented opportunities and new risks.
