This document summarizes several wireless networking standards and protocols used in IoT applications. It discusses protocols for different layers including transport, discovery, data, and device management. Specific standards covered include 6LoWPAN, EPC, WiFi, Bluetooth, ZigBee, and different versions of WiFi (802.11b, 802.11g, 802.11a, 802.11n). Key differences between the standards are highlighted such as operating frequency bands, maximum data rates, and effective transmission ranges. The document provides an overview of the organizational layers in which various IoT protocols operate and the rapid development of new protocols to meet diverse IoT requirements.

 Name : Makarand Badgujar
 MIS : 111409001
 Year & Branch : B.Tech Instrumentation & Control

2. Overview
 IOT- connecting devices, collaborative decisions, acting smartly.
 Various new protocols developing rapidly to meet different IOT requirements.
 The protocols can be classified according to different organizational layers
 Transportation (Data Link )layer concerned with transmission & reception, ack., checksum
 PHY and MAC layer protocols (Combined).

4. ZigBee
 ZigBee Pro 3rd iteration of the standard – Backward
compatible
 Low power wireless mesh network.(Tree, Star)
 Builds on PHY & MAC layer described in IEEE
802.15.4.
 Supports Global 2.4GHz & Region specific
bands.(800 MHz)
 Speed -28 kbps to 250 kbps
 Supports “Application Profiles” which define
protocols for specific applications.
 Suitable for building automation, safety systems etc.

5. Bluetooth
 Standard: IEEE 802.15.1(2002)
 Managed by Special interest Group (30,000)
 Packet based protocol with master-slave architecture
 Uses RF (Radio Frequency)
1. ISM band between 2.4-2.485 GHz.
2. Frequency hopping over 79 channels, 1600
hops/second. (pseudo-randomaly)
3. Each channel uses 1 MHz bandwidth.
 Standard wire-replacement communications protocol.
 Low-power consumption, with a short range.

6. Wi-Fi
 IEEE 802.11(1990)- Revised in 1997
 IEEE modified the standard in 1999 to include: 802.11b, 802.11a, 802.11g (added in 2003)
 a-Commercial and b-home purpose
 Concerned with 2 lower layer of OSI model.
 MAC layer uses CSMA/CA protocol to manage
shared medium.
