What is support layer in IoT?
The fourth layer is considered a support layer (Technologies used in this new layer are cloud computing, intelligent computing, Fog computing etc.) that lie between the perception and network layer of IoT conventional architecture [4, 20, 23]. The perception layer is also called the recognition layer [20].
What is adaptation layer in IoT?
Adaptation layer is present between network layer and data link layer. Large sized. headers like IPv6, UDP and ICMP are compressed by this layer. Also it handles the fragmentation and. reassembly of packets.

According to Statista, there are about 21.5 billion interconnected devices in the world. Their number is set to explode in the following years as internet consumption rises and new gadgets and machinery hit the market.
Which is characteristics of IoT level 5?
A level-5 IoT system has multiple end nodes and one coordinator node. The end nodes perform sensing and/or actuation. The coordinator node collects data from the end nodes and sends it to the cloud. Data is stored and analyzed in the cloud and the application is cloud-based.
What are the different types of IoT model?
We saw that we could do the following to facilitate data processing and intelligence for IoT: Cloud based compute models. Fog based compute models. Edge computing models.
Which is the third layer in IoT architecture?
This architecture consists of three layers: Perception Layer, Network Layer, and Application layer (Figure 3). A brief description of each layer is given: Perception Layer: the main task of the perception layer is to perceive the physical properties of things around us that are part of the IoT.
What is an IoT stack?
The IoT technology stack refers to the range of technologies, applications and standards used to develop an IoT application. It encompasses everything required to build the application, transmit data and generate actionable alerts or other necessary insights.
