Introduction to IoT devicesThe Internet of things is the network of physical devices like smartphone, tablets andgenerally home appliances embedded with sensors, actuators, software and networkconnectivity which enables them to connect and exchange data. Throughout the years,meaning of IoT has developed, their item capacities are expanded and now items can performundertakings past their essential capacity. World has seen a progression of imaginativechanges from autos to office structures to home appliances. [Frew, 2016].Smart dwelling devices:- Day by day internet of things is reaching another level of improvement i.e. form simple housedwelling components to complex products that consists of processors, sensors, software andhardware things. Some smart dwelling devices are: 1.Medical alarm watch - deals with the wellbeing following of your poor onesparticularly your elderly relatives when it is hard to track it physically.2.Smart running shoes - tracks every one of your means like running time, removesecured and so forth. It is implanted with sensors that assistance to track the wellbeingcondition like heart rate.3.Smart wellness attire - is a kind of piece of clothing which has worked in sensors toquantify muscle movement by utilizing method of EMG (Electromyography is aprocedure in which disturbance of muscle tissue is recorded).4.Smart carport controller-deals with the opening and shutting of carport door throughcell phone application. It has additionally highlight of cautioning you if by botch youhave neglected to close it. [Pahwa, 2017].5.Shockbox (Helmet concussion sensor) - are the sensors implanted in defensiveprotective cap of players of any diversion like cricket to gauge the impact of headinfluence. This data of player is sent to parent or tutor's mobile phone by means ofsystem availability which empowers them to settle on fundamental decisions likewhether they should be evacuated off the field.6.Home observation cameras - are a mind boggling approach to assemble security ofyour home. There are couple of items that can normally distinguish development andsend notice to the proprietor's wireless. They are worked for outside and trade therequirement for current light establishment.

Communication Protocols used by Internet of things devicesOne of the crucial factors of internet of things devices are communication protocols. Protocolmakes the link between dwelling devices and enables it to exchange data. Most widely usedprotocols are:-1.6LoWPAN – It is acronym for “IPV6 over Low Power Wireless Personal AreaNetwork.” This IP communication protocol is used in small devices that have limitedprocessing ability to transmit data utilizing internet protocol. It is a type of IPV6protocol. [Ramaswamy, Madakam & Tripathi, 2015].2.MQTT – It is an acronym for “Message Queue Telemetry Transport.” MQTT dependson an open based correspondence show. It is valuable in preserving both power andmemory with most extreme number of subscribers.3.CoAP – It is called as “Constrained Application Protocol.” CoAP is an internetapplication protocol that utilizes wider internet in connection of constrained devices.It is basically client-server protocol that provides one-to-one communication.4.Bluetooth – It is a wireless technology that works over radio frequency. Its working islimited to some specified distance. In this protocol wirelessly audio can be played anddata can be exchanged.5.Cellular network- This is a wireless network that uses 2G/3G/4G protocol to exchangedata.6.WiFi – It stands for “Wireless Fidelity.” It is exceptionally suited for IoT gadgets. Ithas the limit of high measure of information exchange. WiFi can be used for widerdistances using antennas.7.Z-wave – It is type of wireless communication protocol that is particularly utilized forhome mechanization and it requires low power utilization. Its range is over 30 meters.It operates on simpler protocol and does not affect by other protocols like Bluetooth,Zigbee etc.8.Zigbee – It is short range communication protocol based on IEEE standards. Zigbee isused in home automation where low energy consumption is required. It is profitable toutilize this convention on account of versatility, solidness and security.9.RFID – It stands for Radio frequency Identification which uses electromagneticwaves to track the objects. This protocol is specially designed for devices (withoutbatteries) embedded with RFID chips to send signals.

10.Sigfox – It is a wide range technology and which has an edge between cellular andwifi network. It uses ISM bands to transfer data. Sigfox is mainly used thoseapplications which requires low data transfer and has small batteries. Advantages of IPv6In coming years internet of things is going to be the next big thing but without InternetProtocol version 6 (IPv6) is not possible. IPv6 has taken over IPv4 because IPv4 has limitednumber of addresses. IPv6 has numerous numbers of advantages that can lead IoT to a wholenew level. IPv6 provides highly scalable address scheme. With the increasing number of IoTgadgets, IP packet addressing is necessary and Internet protocol version 6 has the capabilityof holding large number of IP addresses. IPv6 takes care of the issue of NAT hindrance bydoling out same IPs to different partners. Partners can send their own applications sharingbasic sensors, without affecting specialized operation or administration of the web.Different types of wireless technology that uses IoT devices1.WiMax – It is the acronym for Worldwide Interoperability for Microwave access. It isa remote innovation in which information can be exchanged at the rate of 40-45megabits for each second. It is based on IEEE 802.16 benchmarks. It can be utilizedboth in inside and outside however it gives better flag when utilized outside.2.Bluetooth and BLE – This are remote advancements that are utilized as a part of shortseparation information exchange. The innovation is a great part of the time used as apiece of little considers contraptions that connect with customer's phones and tablets.For instance, the development is used as a piece of various speaker structures.Bluetooth Low Energy utilizes less power than standard Bluetooth and is utilized as abit of equipment, for instance, health trackers, sharp watches and other relateddevices remembering the true objective to remotely transmit data without stronglyexchanging off the battery control in a customer's phone. It depends on IEEE 802.15.1measures. [Dutton, 2014].3.Zigbee- It is open wireless network used specifically in Machine to machine (M2M)networks. It is the type of affordable and inexpensive technology that uses less power
