Communication between people isunavoidable nowadays; sending and receiving information through internet among people is our daily routine which is known as Internet of People. Hence, this kind of communication has grown even more, making possible to communicate not just people but also things which is known as Internet of Things, one of the trendiest technology. The Internet of Things or IoT refers to the billions of physical devices around the world that are now connected to the internet, collecting and sharing data.The increase of population in urban places and their requirements impose the creation of a system that will satisfy all of these requirements. Due to the increasing number of population the numbers of things that people own has grown enormously. Therefore, this fact generated the idea of adding sensors and intelligence to basic objects. Thanks to cheap processors, wireless network,sensors and actuators is possible to turn anything, from a pill to an aeroplane, into part of the Internet of Things. Combining these digital things in the past was very difficult or barely possible simply because the technology was not ready. The IoT integrates the interconnectedness of human culture- our “things” with the interconnectedness of our digital information system- “the internet”.The development of modern technologies and the Internet of Things establishmentmerged the digital and physical worlds, namely adding digital intelligence to devices that would be otherwise dumb, enabling them to communicate.The potential of this tendencyincreases day by day, enabling a very wide usage. The Internet of Things aims to provide a simple interaction between the physical world and virtual world, integrating a large number of devices of the real world to the internet. The Internet of Things promises to make our environment - our homes,offices and vehicles smarter, more measurable and chattier.The benefits of Internet of Things depend on the particular implementation, but the key is that enterprises should have access to more data about their own things and their own internal system and a greater ability to make changes as a result. It is impossible to predict all IoT applications considering the swift progress of technology and the diversely requirements of consumers. Thus, in our paper we will mention some of the most used and most important applications of IoT, as well the benefits of its implementation in different platforms in different environments. In the end, we emphasize the challenges we face during IoT application, moreoverthe common issues in the adoption of IoT on a large scale.

Cloud Computing seems to be the most promising technology of the century we are living. It provides a new manner of sharing distributed resources and services that may be part of different organizations, geographically located in different places and different time zones. Mobile Cloud Computing offers partially the same functionality, with the only additional requirement that, at least, some of the devices are mobile. In this paper, we will try to provide a detailed explanation of Mobile Cloud Computing concept by providing different examples, figures and charts showing usage, accessibility, pros and cons and comparison of different cloud platforms.
