What’s the Internet of Things
--Internet of Things (IoT) is a computing concept which provides interconnection between the uniquely identifiable devices. 
--By integrating several technologies like actuators and sensor networks, identification and tracking technology, enhanced communication protocol and distributed intelligence of smart objects, IoT enables communication between the real time objects present around us
--From any time ,any place connectivity for anyone, we will now have connectivity for anything!

--In 1997, “The Internet of Things” is the seventh in the series of ITU Internet Reports originally launched in 1997 under the title “Challenges to the Network”.
--1999, Auto-ID Center founded in MIT
--2003, EPC Global founded in MIT
--2005, important technologies of the internet of things was proposed in WSIS conference.
--2008, First international conference of internet of things: The IOT 2008 was held at Zurich.

Cisco’s Prevision about IoT
--Cisco’s Prevision about In 2008 the number of things connected to the Internet was greater than the people living on Earth.
--Within 2020 the number of things connected to the Internet will be about 50 billion.

IoT Communication Features

Technologies Involved

--Data Brokers/Cloud
--Machine Learning

-A radio-frequency identification system uses tags, or labels attached to the objects to be identified. Two-way radio transmitter-receivers called interrogators or readers send a signal to the tag and read its response.
-RFID tags can be either passive, active or battery assisted passive.
-Frequency: 120–150 kHz (LF), 13.56 MHz (HF), 433 MHz (UHF)
-Range: 10cm to 200m

-ISO/IEC14543-3-10 (Alliance)
-A The EnOcean technology is an energy harvesting wireless technology used primarily in building automation systems; but is also applied to other applications in industry, transportation, logistics and smart homes
-Frequency: 315 MHz, 868 MHz, 902 MHz
-Range: 300m Outdoor, 30m Indoors

-ISO/IEC18092 and ISO/IEC 14443-2,3,4
-NFC is a set of short-range wireless technologies, typically requiring a distance of 10 cm or less.
-NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target.
-Frequency: 13.56 MHz
-Range: < 0.2 m
-Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band.
-Frequency: 2.4GHz
-Range: 1-100m
WiFi (Alliance)
-The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards.
-Frequency: 2.4 GHz, 3.6 GHz and 4.9/5.0 GHz
-Range: Common range is up to 100m but can be extended.
Weightless (SIG)
-Weightless is a proposed proprietary open wireless technology standard for exchanging data between a base station and thousands of machines around it using White space with high levels of security.
Frequency:Varies with legislation (470 – 790MHz)
Range: Up to 10km
Data Rates: 1kbits/s to 10Mbits/s

GSM (Association)
-GSM (Global System for Mobile communications) is an open, digital cellular technology used for transmitting mobile voice and data services.
-Frequency:Europe:900MHz & 1.8GHz , US: 1.9GHz & 850MHz
-Data Rates: 9.6 kbps

--Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.
--IPv6 uses a 128-bit address, allowing 2128, or approximately 3.4×1038 addresses, or more than 7.9×1028 times as many as IPv4, which uses 32-bit addresses.
--With UDP, computer applications can send messages, in this case referred to as data-grams, to other hosts on an Internet Protocol (IP) network without prior communications to set up special transmission channels or data paths.
--The Transmission Control Protocol (TCP) is intended for use as a highly reliable host-to-host protocol between hosts in packet-switched computer communication networks.
--6LoWPAN is an acronym of IPv6 over Low power Wireless Personal Area Networks. 
--The 6LoWPAN group has defined encapsulation and header compression mechanisms that allow IPv6 packets to be sent to and received from over IEEE 802.15.4 based networks.
--It contain issues such as small packet sizes, low bandwidth, low power, large volumes of devices, unreliability from radio connectivity issues, battery drain, device lockups, and physical tampering.

-Wireless SoC (system on chip)
-Self-contained,RF-certified module solutions that have TCP, UDP and IP on chip.
-Manufactures:  Gainspan, Wiznet, Nordic Semiconductor, TI
-Prototyping boards and platforms
--Raspberry Pi
--BeagleBone Black
-These are communities and prototyping platforms available that are making its possible to create your own Internet of Things project.
-Sensors are used to obtain measurements of physical parameters such as the presence of certain biological entities (biosensors), wavelengths of light (image sensors), and flow velocity (thermal flow sensors) etc.
