IoT protocols can be broadly divided into four main layers namely, the physical and MAC layer, the network layer, the transport layer and the application layer as shown in Fig. 1.

6 days ago · The architecture of IoT is divided into 4 different layers i.e. Sensing Layer, Network Layer, Data processing Layer, and Application Layer. Sensing Layer: The sensing layer is the first layer of the Internet of Things architecture and is responsible for …

Jan 26, 2017 · Communication in the IoT world requires special networking protocols and mechanisms. Therefore, new mechanisms and protocols have been proposed and implemented for each layer of the networking stack, according to the requirements imposed by IoT devices.

The present paper proposes a hybrid model for the detection of attacks in an IoT environment that involves three stages. Initially, the higher-order statistical features (kurtosis, variance,...

As illustrated in Fig. 2, we adopt and analyze the security issues of the IoT in a four-layer architecture which consists of: (1) Perception Layer, (2) Communication Layer, (3) Sup- port Layer...

Sep 13, 2024 · Gateways are responsible for transmitting data of an IoT system through the internet. They modulate and demodulate the data for transmission. Gateways help to transmit the data from the processor of the IoT system to the server for storage. Gateways use a standard protocol system (ex: MQTT, XMPP) for data transmission.

Mar 9, 2021 · Communication models used in IoT have great value. The IoTs allow people and things to be connected any time, any space, with anything and anyone, using any network and any service. Types of Communication Model : 1. Request & Response Model –. This model follows a client-server architecture.
