The IoT protocol stack can be visualized as an extension of the TCP/IP layered protocol model and is comprised of the following layers: physical layer, link layer, network layer, transport layer, application protocol layer, and application services layer. ZigBee uses the following devices in its network: LoRaWAN refers to Long Rage Wide Area Network which is a wide area network protocol. Application layer protocols founded on TCP and UDP solve the communication challenges faced in an IoT project. Section 4 gives a comparison about short and long range IoT link layer protocols arising from their main characteristics. Developed by JavaTpoint. Some of the popular Standard IoT communication protocols are: Attention reader! The Session Layer manages connection between two endpoints of a network by controlling data between sender and receiver where session layer protocols are responsible for actual transmission of data in IoT ecosystem. 2. The Open Systems Interconnection (OSI) model is an ISO-standard abstract model is a stack of seven protocol layers. The Bluetooth communication network works within 2.4 ISM band frequencies with data rate up to 3Mbps. BLE always remain in sleep mode except when the connection between devices is initiated and data transmission occurs, due to this it conserves power of the device. The link layer is the lowest layer in the TCPIP model. long range link layer protocols is p resented in S ection 3. Bluetooth is a short-range wireless communication network over a radio frequency.
