IoT Wireless Network Protocols
In the Internet of Things (IoT), the interchange of data among sensors, devices, gateways, servers, and user applications is enabled by network protocols like WiFi, Bluetooth, ZigBee, and many others. End Application requirements of range, data, security, power, and battery life dictate network protocol choice. This article explores some of these communication technologies and protocols.
An IoT ecosystem typically consists of nodes, data, connectivity, and application layer. The node layer is a coalition of smart devices such as microcontrollers, microprocessors, sensors, actuators, connectivity, and gateways interacting with a network.
The data layer is concerned with the data collected, processed, sent, stored, analyzed, presented, and used in business contexts. The application or user layer is the component that allows humans to interact with IoT devices. We will discuss the connectivity layer which comprises of communication and IoT protocols.

IoT Protocol Types
The Internet Protocol's (IP) inherent adaptable and dependable nature makes it an acceptable medium for procedural transmission among IoT modules. The system architecture (through which the data must travel) determines the IoT protocol type. The Open Systems Interconnection (OSI) model delivers a map of the various layers that dispatch and accept data. Each protocol in the IoT system architecture enables device-to-device, device-to-gateway, gateway-to-data center, gateway-to-cloud communication, and communication between data centers. Figure 2 shows the IoT Protocol stack.
