IoT architecture
A typical IoT architecture can consist of many physical objects connected to each other, and to a centralized cloud server. This is shown in the following diagram:
Figure 22.1: A typical IoT network
Elements of the IoT are spread across multiple layers, and various existing reference architectures can be used to develop IoT systems. A five-layer model can be used to describe IoT, which contains a physical object layer, a device layer, a network layer, a services layer, and an application layer. Each layer or level is responsible for various functions and includes multiple components. These are shown in the following figure:
Application layer Transportation, financial, insurance, and many others |
Management layer Data processing, analytics, security management |
Network layer LAN, WAN, PAN, routers | ...
