ABSTRACT: The communication is the process of sending and receiving messages through signs or language or behavior or any other medium. Presently the communication is done through human to human via using sound as a medium to transfer the information, thoughts expression by modulating the sound’s pitch and amplitude or through non-verbal communication of information. The growth and development of technologies has done a great job to make user communication more efficient and affordable. The new generation is having lots of devices, tools and gazettes to facilitate this where message through sound is not much required in mobile devices SMS or MMS and new app like Whatsapp is giving all the facility of sending message with all expression by using Internet.Internet is a big and important media and backbone for communication among devices or things, there are billions of machine and in future those machines will communicate with each other using internet so that the life of human will become more comfortable. In this paper the author(s) are going to elaborate the picture where the things and devices are communicating and what will be the next future of the communication world. Keywords: - IoT, D2D, M2M, H2H, IoE, Generation of Internet, applications

I. INTRODUCTION The history of communication is as old as mankind, we are making the things understand to other people by means of verbal and non-verbal communication. The face of communication is changed due to technological up gradations, in earlier times we used to send signal through fire or smoke to inform or warn from danger now this information can be done through a single “tap” on smartphone devices and to the concern person only. We are able to understand to each other by the means of communication, in contemporary scenario the means of communications are changing we are moving ahead in terms of technology and population. The need of stay connected is a

human nature and it is becoming possible by using fast data transfer through using technology. The communication technology has evolved through many steps from very limited connectivity to super-fast connectivity. As the time travels the need of human being is growing and to satisfy the need of communication humans are using various technologies to maintain the urge. IoT, IoE, D2D etc. are the means of achieving the same. Communication is not only necessary in terms of stay connected with family or friends but also important in terms of commercial transaction and marketing. With technological updation companies are able to maintain the inventory, stocks and logistic channel, people are finding new ways to tap the market and customer needs, many new companies are upcoming with new ideas and concepts to ease out the need of mankind. Online purchasing through mobile devices and computer were not possible 20 years from now, Internet has become the backbone of faster communication, the development of Internet itself in terms of connectivity and reliability has given a major support to these kind of ventures. People are purchasing the products and services online to save the time and money, people are getting real time data to modify the price or offers associated with that product in real time. The ultimate goal of selling the product to the customer by understanding the “needs” of customer in real time that is made possible through technology. In the forthcoming part of the paper we are going to understand the technologies and how these technologies are going to change the future of communication and understanding changing customer needs in contemporary scenario.

II. INTERNET OF THINGS (IoT) The Internet of Things (IoT) is the network of physical objects or "things" embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data. The Internet of Things allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration between the physical world and computer-based systems, and

In IoT the 'things' could be a person with a heart monitor or an automobile with built-in-sensors. In IoT the objects have been assigned an IP address. We are having IPv4 already and our electronics devices suchas laptops and personal computers are becoming more sophisticated to communicate on IPv6, with IPv6 we would be able to take care of the IP addresses to almost for everyone. The big difference between it and IPv4 is the increase in address space. IPv4 addresses are 32 bits; IPv6 addresses are 128 bits .By using IPv6, we are having a huge number of IP addresses to cater the need for IoT kind of upcoming technology [2].The object collects the data and transfer it over a network without intervention. The embedded technology helps them to interact with internal states or the external environment, which in turn affects the decisions taken. Thus, IoT is the technique in which we connect the internet with the things which we use or see in our day to day life . IoT is expected to offer advanced connectivity of devices, systems, and services that goes beyond machine-to-machine communications (M2M) and covers a variety of protocols, domains, and applications. The interconnection of these embedded devices (including smart objects), is expected to usher in automation in nearly all fields [1].

M2M is considered an integral part of the Internet of Things (IoT) movement, and the term is widely used by industry experts. When a machine communicates with another machine to accumulate information and exchange data, then it is called machine to machine communication. It may use various wireless and wired networking. In recent days machine to machine communication includes the transmission of data to personal appliances. M2M that will bring a revolution in different sectors for example: security, emergency services, marketing etc. Machine-to-Machine (M2M) technology is here to stay and will continue to be one of the fastest growing areas in technology both in enterprise and consumer markets. Devices like the Apple Watch are not only capable of telling time and providing restaurant recommendations, they also come with sensors that monitor activities, capture data and report information back to other devices or applications all without much human intervention [3]. In present time we use CCTV cameras in secret places, and after accidents by the camera recording we can recognize the culprit.But in future when m2m communication will take place, we will put some trusty people’s picture in camera memory ,and if a camera capture a person who is not one of that trustworthy pictures then camera will immediately communicate with the security alarm, and the alarm will rang and alert us, then we can stop the accident before its happen. This is what m2m communication. III.I. THE VALUE OF M2M Growth in the M2M and IoT markets has been growing rapidly, and according to many reports, growth will continue. Strategy Analytics believes that low power, wide-area network (LPWAN) connections will grow from 11 million in 2014 to 5 billion in 2022. And IDC says the market for worldwide IoT solutions will go from $1.9 trillion in 2013 to $7.1 trillion in 2020.Many big cell operators, like AT&T and Verizon, see this potential and are rolling out their own M2M platforms. Intel, PTC, and Wipro are are all marketing heavily in M2M and working to take advantage of this major industry growth spurt. But there is still a great opportunity for new technology companies to engage in highly automated solutions to help streamline processes in nearly any type of industry[4].

Human to human communication has a long history from the origin of mankind to till now. When a human communicates with human via signs and languages, this is called human to human communication. In this world humans are communicating to each other by different kind of languages and each and every language has its own rules, regulation and syntax. The basic thing all the languages do is that to communicate the data or information from one person to another.

Some enabling technologies for IoT are, RFID or near field communication, Optical tags and quick response code, Bluetooth low energy.

M2M, D2D, IoT etc. are the fastest growing technology for our future, but without H2H, we will never be able to unlock its full potential. M2M will always call for H2H. M2M implementations without H2H cannot generate the expected returns unless humans are able to defy distance instantly to address issues, solve problems and handle cases. Every organization looking at M2M implementations must also look at how employees can collaborate and connect with clients, customers, patients, citizens, or even students regardless of location.

Fig.3: Pictroial representation of Human to human communication https://www.google.co.in/url?sa=i&rct=j&q=&esrc=s&source=images &cd=&cad=rja&uact=8&ved=0ahUKEwispojpzrJAhWBBY4KHRy4DiIQjRwIBw&url=https%3A%2F%2Fmishahlin i1996.wordpress.com%2Fabout%2F&psig=AFQjCNFINyAUlw32Av m-byHtrlMftUuMSA&ust=1450707241055267

Face-to-face interactions are vital when collaborating with peers and communicating information to others. The human element:tone of voice, body language, facial expressions are essential, because we are not machines. As such, using an H2H approach can lead to impactful results for a wide variety of industries. Pharmaceutical companies, for example, can accelerate innovation, product quality and ensure compliance to legal requirements. Software and game developers also improve collaboration with platform vendors. Retailers improve training and customer experience in store, and financial service companies improve customer retention through first call resolution with a human touch. Even schools and universities

The major advantages of human to human communication is it has High level of understanding, No element of rigidity, it is best to transfer confidential information. If we talk about the Disadvantages of Human to human communication, Actually human to human communication is not possible always due to human ‘s own limitations . Talking between two human is best way to communicate but if two persons or more than two persons talk at a time makes the scenario worst and the distance between them plays an important role in understanding between them. In human to human communication, there is a chance of prejudices or unfair intentions. Human beings are making conversation and departing information and data through verbal and non-verbal communication from a long time ago. However, all the technological updatation and tools will need human touch at some stage of communication.

V. DEVICE TO DEVICE (D2D) COMMUNICATION If we want to avoid the routing via enodeb and core network then we can use the proximity services to directly transmit the data. It is called D2D communication& it has different structure which is different from that of a traditional cellular network.

D2D communication is a communication in which devices communicate with each other and devices are using frequency spectrum or sharing frequency spectrum for its maximum advantage. It is a peer 2 peer application and communication. In it we uses the frequency spectrum sharing to transmit the data which has many advantages. it improves overall throughput, spectrum utilization, and energy efficiency. Another prominent feature is , it will work even when the network system is down due to any reason.. It will be a proximity based connectivity between two devices which will help in following sectionsi) human communication through devices in terms of social networking and entertainment and gaming purposes, ii) it will help in marketing and advertisement for travelers by

By having such type of interconnectivity we will have faster communication in emergency time. Like fire etc We are entering into the era of fast communication networking where the data and information is spreading at the fast speed it is possible by using latest generation of mobile technology like 4G, LTE and 5G, where the data in Gigabytes can be transferred in minutes. If we talk about the latest technology one of them is LTE. LTE, an abbreviation for Long-Term Evolution, commonly marketed as 4G LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals [5]. As the communication standards have been upgraded people are using high end technological updated services such as web browsing, streaming, social media apps and others and it required higher data rate to transmit the information between the devices. The Increased data rates of carrier aggregation can be traded off to get higher capacity for heavy applications, meaning operators can choose a higher capacity spectrum to transmit the data for giving the user a better experience. People are also working on 5G of mobile communication where the data will travel from one device to another at more faster and safer.

VI. INTERNET OF EVERYTHING (IoE) Any Machine. Virtually Anywhere. Always Connected. The Internet of Everything (IoE) is the next evolutionary stage of the Internet of Things (IoT). The Internet of Everything describes the networked connections between devices, people, processes and data.

network or other devices. Many of these use cases demand 3G/4G LTE connectivity to reliably manage machines, virtually anywhere, 24/7. LTE benefits from the ubiquitous coverage, unparalleled availability, and robust security inherent of 4G LTE. IoE which connects not just physical devices but quite literally everything by getting them all on the network. It moves beyond being a major buzzword and technology trend by connecting devices to one another and the Internet, and offers higher computing power. This connection goes beyond basic M2M communications, and it is the interconnection of devices that leads to automation and advanced “smart” applications. IoE works to connect more devices onto the network, stretching out the edges of the network and expanding the roster of what can be connected. IoE has a major play in all industries, from retail to telecommunications to banking and financial services. Connecting the Internet of Everything requires different types of wireless connectivity to support a wide range of performance, cost, and energy requirements. Powered by global standards like Bluetooth, Wi-Fi, and 4G LTE, that deliver seamless interoperability across multiple vendors. IoT, IoE, D2D, M2M are able to communicate with and without human intervention by using fast internet connectivity. We are using 3G till now, next phase is of 4G/LTE (long term evolution) and next expected internet technology is 5G. 5G has more capacity than its earlier versions and more capability to connect millions of devices/things to transfer the data over IPV6. Due to this there are many applications and product could be offered in the market each tools like IoT, IoE etc. are coming almost everything on that level of connectivity real time base products/services can be offered by using these tools the future of communication and market will be changed to next dimension which was not available in 2G phase or earlier.

Internet connects whole world of computers and other things like mobile devices to each other to transmit data. They talk to each other through pre-defined protocols in earlier stage of Internet connectivity the speed of data transmission was the bottleneck that is evolved eventually through time and technological updataion, if we look at the generation of Internet we can say that the development of quality and efficiency is commendable by using fiber optics cable and wireless internet connectivity through 4G and coming up 5G connectivity it is capable of connecting each and every devices on the planet. Moreover, the other technological things like tools which are using the base of internet like IoT, D2D, Cloud computing etc. have immense power to deliver services to the mankind which were beyond the thought like real time data transfer at very good speed, life of battery of mobile devices and connecting sensors and many more. By using these tools human being are benefiting and more product and services market are being developed. To stay connected to each other by means of talking

Internet telephony, real time messaging and data transfer are sore features of above said applications.

COMPASS system is developed by China. The Galileo System is developed by EU, and the GLONASS system is developed by Russia. These independent systems are difficulty for space roaming. The task of 7th generation (7G) wireless mobile communication networks are going to unite the four systems to get space roaming.

VIII. THE GENERATION OF INTERNET The Internet can be classified into three generations on the basis of the technology it uses and the applications it supports. Most of the Internet users use the first generation internet. But the inefficiency and congestion on this internet has become unacceptable to perform any research activities. The first generation Internet has the following features: • Unreliable • Uses IPv4 • No Quality of Service • No assured Bandwidth • Very low speeds The second generation is a major step towards developing the Internet. This development which has so far been only in the research area is moving to the implementation area. The Second generation Internet adds quality of service, multimedia and other advanced services to the current Internet. The second generation internet initiatives are I2, NGI, CAnet2 and other Asian networks. The chief characteristics of the second generation Internet initiatives are: • Uses IPv6 • Multicast is provided • QoS is provided Third generation Internet provides all the advanced features at a very fast speed. The third generation Internet is mainly in the research stage. It involves many ambitious projects that are being done in the level of a local area network and are expected to be implemented in a global way. The third generation internet initiatives are the CAnet3, SUPERNet. The chief characteristics of the third generation Internet are: • Use of DWDM and other optical technologies • Usage of optical layer routing and switching The 4th Generation (4G) wireless mobile internet networks are research items in academy, which will integrate current existing 3G cellular networks (i.e., OFDM, CDMA2000, WCDMA and TD_SCDMA) and Wi-Fi (i.e. Wireless LAN) networks with fixed internet to support wireless mobile internet as the same quality of service as fixed internet, which is an evolution not only to move beyond the limitations and problems of 3G, but also to enhance the quality of services, to increase the bandwidth and to reduce the cost of the resource. The 5th wireless mobile multimedia internet networks can be completed wireless communication without limitation, which bring us perfect real world wireless – World Wide Wireless Web (WWWW). 5G is based on 4G technologies, which is to be revolution to 5G.During this processing, there are two kind of problems need to be solved. The first is wider coverage and the second is freedom of movement from one technology to another. The 6th generation (6G) wireless mobile communication networks shall integrate satellites to get global coverage. The global coverage systems have been developed by four courtiers. The global position system (GPS) is developed by USA. The

These are the analog telecommunications standards that were introduced in the 1980s and continued until being replaced by 2G digital telecommunications. The main difference between two succeeding mobile telephone systems, 1G and 2G, is that the radio signals that 1G networks use are analog, while 2G networks are digital. Although both systems use digital signaling to connect the radio towers (which listen to the handsets) to the rest of the telephone system [6]. Many developed and developing countries like US, Europe, China etc. are working upon the Internet technologies and having big budgets to develop these technologies. The next generation of Internet is used by the next generation of young people who are utilizing the maximum advantage of Internet and smart mobile devices. The next generation can be called as Internet generation of the youth. IX. APPLICATIONS IX.I.
